Hybrid Nanoparticles Derived from Diamonds Show Promising Developments

nanodiamondNanotechnology is now being developed for the hopes that it will improve other technologies that will be developed in the near future. This includes improving computer chip performances, better imaging from medical devices, and more power- efficient electrical devices.

Researchers from University of Maryland have come up with a procedure of creating large quantity of hybrid nanoparticles derived from diamonds. With their new procedure, they are able to bypass the existing problem that they’re experiencing while trying to make this kind of nanoparticle.

The method gives a different composition into diamond’s molecular structure. Instead of a carbon atom, the researchers place a nitrogen atom and an empty space beside where another carbon atom should be. This gap is called “nitrogen vacancy impurity” that resulted to different electromagnetic and optical properties of the diamond.

With this impurity, the researchers can put a different atom in that gap to incorporate different metal particles, called as ‘quantum dots’, and create different kinds of hybrid nanoparticles than can be used for different devices with specific nano properties.

Min Ouyang, the senior author of the study and an associate professor of Physics at University of Maryland, said “If you pair one of these diamonds with silver or gold nanoparticles, the metal can enhance the nanodiamond’s optical properties. If you couple the nanodiamond to a semiconducting quantum dot, the hybrid particle can transfer energy more efficiently.”

Results of their study also shows that this hybrid nanotechnology can work as a quantum bit, also known as qubit, even with the absence of ultra- low temperature. The researchers are hoping that their new method can use hybrid nano as qubit in room temperature. If they are able to succeed with this new development, it can change and improve the way how we process and store information.

Ouyang also said that if their new method permits qubit to work in room temperature, quantum circuits and components will soon be used in different electronics and even with household devices. With all these promising possibilities, the researchers are still focusing their efforts in replicating their work of producing hybrid nanoparticles using diamond grains. “Our key innovation is that we can now reliably and efficiently produce these freestanding hybrid particles in large numbers,” he said.

Researchers have used artificially- created diamonds for their study so they can customize its chemical composition put one nitrogen vacancy. This alteration caused the impurity that separates it to the molecular structure of pure diamond that consists of arranged frame of carbon atoms.

“A major strength of our technique is that it is broadly useful and can be applied to a variety of diamond types and paired with a variety of other nanomaterials. It can also be scaled up fairly easily. We are interested in studying the basic physics further, but also moving toward specific applications. The potential for room-temperature quantum entanglement is particularly exciting and important,” Ouyang added.

Though there are still a lot to improve when it comes to nanotechnology, we can expect great developments in the next few years as things are looking up on the bright side of things.

 

The Use of Nanotechnology in Targeted Chemotherapy

nanotech

Cancer is one of the deadliest illnesses known to men. Researchers, scientists, and doctors around the globe are teaming up to gather enough data on how they can prevent, cure and eradicate it. One of the basic steps in preventing it is having a healthy lifestyle. However, there are rare cases where people with healthy lifestyles are still being diagnosed with cancer.

One of the most common treatment of cancer is going through chemotherapy where the medicine being injected will kill the cancer cells. However, it will also destroy even the healthy cells that’s why patients who have decided to undergo through it need medical supervision all the time during medication.

Due to the side effects of chemotherapy, medical researchers and scientists are developing new methods where the chemotherapy drug will be administered directly to the cancer cells or tumor to avoid destroying healthy cells in the body. The methods are said to be used with nanotechnology.

The drug for killing cancer cells is called tumor necrosis factor alpha which is being administered together with a nanoparticle of gold. Also, Thiol-derivatized polyethylene glycol is included to the drug as it serves as a camouflage so our body’s immune system won’t attack the foreign particle inside our body. Another method being developed is using nanoparticles to generate heat and attacking the cancer cells. A nanoparticle called AuroShells will convert light into heat after absorbing it from a laser.

University of Georgia is able to conduct an experiment of using nanotechnology in combatting prostate cancer. In one of their experiments on mice, the nanoparticle brings a molecule called IPA- 3, which happens to hinders the growth of the cancer cells in the prostate.

MIT researchers are also conducting their own research in using nanoparticles in targeting cancer cells. Their study focuses on using nanoparticles in administering three different drug in three specific ratios to the cancer cells. Their experiment is also focused in ovarian cancer cells.

UCLA researchers introduced a different method in their research of treating pancreatic cancer by using two different nanoparticles in which one of it will destroy the outer lining of a cancer cell, especially the material that hinders the administration of the anti- cancer drug into the cell itself. Once the outer membrane is already breached, the second nanoparticle will then administer the drug directly inside of the cancer cell. They have tested this development on laboratory mice and significant change is observed as the tumor reduces faster than the usual administration of chemotherapy drug.

A company called BIND Biosciences are also developing a method where polymer nanoparticles are being used in delivering chemotherapy drugs. These specific nanoparticles are normally attracted to the protein that can be found in most cancer cells. With this in consideration, we can now increase the rate of drugs being delivered to the cancer cells itself.

Another study found out that leukemia cancer cells can be resistant to chemotherapy drugs by pushing it out of the cancer cells. However, it cannot push out nanodiamond and attaching the chemotherapy drug to it will allow the drug stay longer on the cancer cells which can greatly help the drug to do its job.

A lot of studies are now being conducted and they are using nanotechnology in improving chemotherapy which is our best weapon yet against cancer.

Nano Particles

As nanoparticles become increasingly important in our everyday lives, the understanding of nanoparticles remains shrouded in mystery to most people.  This article attempts to explain the types and uses of these small objects.

In nanotechnology, particles are classified according to size — this includes the diameter of a particle.  Within these tiny particles the sizes are defined as coarse or ultrafine.

These “nanoparticles” cover a range of sizes:

Coarse – between 10,000 and 2,500 nanometers

Fine – between 2,500 to 100 nanometers

Ultrafine – between 100 to 1 nanometer

Individual molecules are usually not referred to as nanoparticles even though the size of most molecules would fit into the above classifications.  Currently, research and a growing interest surround these tiny particles.  This is due to the massive opportunity in the commercial sectors as well as the growing case for human prosperity.  Scientists think that nanoparticle development will lead to huge leaps in technology — particularly in electronic, optical, and biomedical areas.

Nanoparticles are considered to be a more recent undertaking of modern science, however, early artists and craftsman used nanoparticle technology for metallic applications.  This luster method demonstrated a complex knowledge that ancient people had of materials.

Currently, there are active uses of nanoparticle technology.  One such use is the carrying of a chemotherapy drug which helps transport the drug in a direct path to cancerous tumors.  The particles respond to a protein found within many types of tumors which creates a high delivery rate for the drug.  This is being actively studied in Biosciences.  In another use for cancer, gold is used used along with RNA molecules.  The skin treatment that is developed can get through the skin and stop generation of proteins which inhibits further growth.  There are many more applications being used with this type of delivery mechanism including magnetic attaching to cancer cells.

Nanoparticles are also being used as sensors and transistors.  This provides them with wide electronics functionality — however, producing these tiny components still costs a lot of money.  This is just the beginning of the wide uses of this technology.

Here are some more uses:

– Industrial coatings (for protecting things from ultra violet rays)

– Strengthening structures for lightweight applications

– Bacteria resistant for making textiles and fabrics odor/grime resistant.

– Crcuitry for making smaller and smaller “smart” parts

– Solar cells can be made from a nanoparticle printing process

– Reclamation of clean water by removing poisons such as arsenic from water sources

The most revolutionary use of all would be the delivering of genetic therapy.  After studying nanotechnology and nanoparticles, it is easy to see how these tiny particles have the ability to create some influential things.  Scientists speculate on future uses — paving roads with solar cells, delivering cancer curing medicine with lotion (already happening), diagnosing patients with invisible-to-the-human-eye robots, all made up of these tiny little particles.  The future is bright and soon we can look forward to more consumer uses of these nanoparticles.

What is Nano Science?

Nano science, when you break down the term, comes from two words. There’s the Greek word, “nanos,” which means dwarf, and another word we’re already familiar with, science. Simply put, it adds up to ‘science of the small.’ Specialized scientists primarily study objects that — when measured by what’s called a nano meter scale — are between 1 and 100 nano meters in size.

The study of nano science is more than just the ability to better see and quantify small things, however. By becoming more educated about molecular properties, scientists are more able to put elements together in better defined ways in order to create new materials with previously unforeseen values.

So, in practical terms, nano science can be applied to a wide variety of fields. For instance, it can be used in food processing to improve ingredients, such as flavoring. It can also be incorporated to enhance how edibles are colored. Even more importantly, nano science can be helpful to medical fields. A good example of this application is how nano science can aid in the discovery of cancerous bacteria in the human body, particularly at early stages. Did you know that blood thinner, which is necessary to regulate blood level in the body, is yet another use of nano structure particles? Without a doubt, doctors appreciate nano science.

Even manufacturers in Detroit design car and truck brakes to be more effective by improving the liquids used in disc brake systems. Nano science is also applied to making engines stronger. Furthermore, auto builders have discovered that nano paint for cars makes vehicles much more water and dirt resistant, and also decreases scratches and chips. Aesthetically, nano paints make for brighter colors and glossier finishes. You could say the motor city is also becoming much more nano-scientific.

Nano science may be the study of small things, but this expanding field is expected to grow even larger in the near future. It’s anticipated to comprise approximately 15% of global manufacturing output in just a few years, and will soon be worth multiple billions of dollars. Before long, nano science will make up half of electronic manufacturing alone, for instance. The United State is expected to invest millions of dollars in nanotechnologies related to cancer research over the next five years. Clearly, there is big money in this science of the small.

Of course, you don’t even have to be a science buff to be exposed to nano science. If you think about it, DNA — the tiny essential molecule that carries our genetic blueprint — may well be the ultimate natural tool for nanotechnology. If you watch one of those CSI shows on television, or just about any detective show for that matter, you will almost certainly hear DNA evidence discussed. And let’s not forget that cop shows are based on real life crime stories. The newspapers and TV news programs are filled with stories about criminals that have been caught because of DNA evidence, or convicts set free from prison because DNA evidence vindicated them. If you stop and think about it, the use of nano science is nearly everywhere.

Much like the Dr. Seuss story, Horton Hears a Who, nano science proves that just because something cannot be seen with the naked eye, doesn’t mean it’s not extremely important. Rather, once particles can be seen for what they truly are, only then can they be fully appreciated, studied and utilized. The existence of nano science is a reminder that a little can go a long, long way.

Nano Materials

Application of Nano Materials

Scientists have studied nano materials since the turn of the century. Even though research has been done on these very unique materials, the world is yet to see extensive real world applications as was anticipated when its research began almost a hundred years ago. The slow implementation of it in the real world is probably due to safety concerns about the adoption of nano technology in health applications.

A good the percentage of real life application of nano technology is in health. Unfortunately, this is where most of the concerns on its safety are concentrated. Research on health requires a considerably long period of time in order to ensure that it is safe.

However, there have been a good number of nano products that can be found in the market. The nano products that have found their way into people’s homes range from clothes, tennis balls, water resistant clothes and car wax that can give your car a better shine. Nano materials have unique properties that are different from other materials. Their size gives it structural strength that makes it possible to make stronger and more durable products. The size is also applied in photography and plasma and LCD TV screen to provide a shaper and better quality image. Here are some of the applications of nano technology that have found their way into people’s homes.

Sonax Nano Technology Liquid Wax: The purpose of making a nano car wax is twofold: to provide a better shine and to protect the car’s paint. The wax will give a better shine than ordinary car wax because it works at the microscopic level. However, for you to realize the full benefits of using a nano car wax you will have to use a micro fiber material to apply the paint.

The other benefit of A nano car wax is to protect the car’s paint. The wax when applied onto a car’s body will find its way into the microscopic spaces that have been left on the car’s body work. This not only helps to protect the paint, but also the body of the car by filling up in those tiny spaces not covered by the car’s wax. Furthermore, the wax is known to last longer and so this is another way it works to protect the car.

Meguiar’s EvenCoat Applicator: This applicator is made of micro fibers and is the best material to be used with the nano liquid wax to ensure an even application of the wax. It can be cleaned like a regular towel and used again later. If you have nano wax you can add this to your kit in order to make it complete.

Clarity Defender® PLUS Automotive Windshield Treatment: This windshield film is invisible and is used to prevent rain, bird droppings and bugs from sticking onto your windshield. Research has shown that this film gives 34% better visibility when it’s raining or snowing. The nano technology will also help the driver get rid of bird droppings faster. The clarity defender goes for about $15 and can be expected to last for 8 to 10 months.

What are Nanoparticles

An ultrafine nano particle (or nano powder or nano cluster or nano crystal) is a microscopic particle sized between 100 and 1 nano meters.  In modern science Nano particle research is currently an area of intense scientific research owing to its potential in wide range of applications in bio medical, optical and electronic fields.  When formed from nano particles the properties of many conventional materials change because nano particles have a greater surface area per weight than larger particles; this causes them to be more reactive to certain other molecules.

Nano particles exhibit numerous interesting and unexpected properties relative to bulk materials.  Copper nano particles smaller than 50nm are considered super tough materials that do not exhibit the same malleability and ductility as bulk copper. For instance, the bending of bulk copper like wire or ribbon occurs with movement of copper atoms/clusters at about 50nm scale.

As Nano particles are minuscule enough to confine their electrons and produce quantum effects, they often have unexpected visible properties! For example gold nano particles appear deep red to black in solution as they have a very high surface area to volume ratio.

Nano particles in medicine: An estimated 130 nano tech-based drugs and delivery systems are being developed worldwide. A method being developed to fight skin cancer uses gold nano particles to which RNA molecules are attached. The nano particles are in an ointment that is applied to the skin. The nano particles penetrate the skin and the RNA attaches to a cancer related gene, stopping the gene from generating proteins that are used in the growth of skin cancer tumors. Polymer nano particles are being developed to carry the chemotherapy drug called docetaxel directly to cancer tumors. The nano particles are attracted to a protein present on many types of cancer tumors, resulting in a high rate of delivery of the chemotherapy drug to the tumors. To reduce bleeding in trauma patients with external wounds Researchers have found that aluminosilicate nano particles can by activating the blood clotting mechanism, causing blood in a wound to clot quickly. For trauma patients with internal bleeding another way to reduce the blood loss is needed. Polymer nano particles that act as synthetic platelets are being developed by Researchers at Chase Western Reserve University. It was proven by Lab tests that the injection of these synthetic platelets significantly reduces blood loss. Nano particles coated with proteins that attach to damaged portions of arteries. This could allow delivery of drugs to the damaged regions of arteries to fight cardiovascular disease.

History: Nano particles actually have a very long history, though considered an invention of modern science. In the 9th century Nano particles were used by artisans in Mesopotamia for generating a glittering effect on the surface of pots. The ancient artisans had a rather sophisticated empirical knowledge of materials. The luster was created by a metallic film that was applied to the transparent surface of a glazing. This luster is visible even today in certain cases where the film has resisted atmospheric oxidation and other effects of the elements.

In his classic 1857 paper, Michael Faraday provided the first scientific description, of the optical properties of nano meter-scale metals.

Nano Biotechnology

Nano biotechnology is basically miniaturized biotechnology. It is the intersection of nanotechnology and biology, in other words. Since nanotechnology involves extremely small scale technological practices, and because living organisms are equally broken down into small parts, the marriage of these two studies is a proverbial match made in medical heaven.

A good example of nano biotechnology is DNA nanotechnology, which is also sometimes called cellular engineering. DNA fits under the nano biotechnology umbrella because it utilizes bio molecules on the nano scale, and further advances biological goals.

Speaking of DNA, perhaps the most important developments in nano biotechnology involve modern medicine. In this essential field, it’s used to treat symptoms in order to generate cures for the regeneration of biological tissues. For instance, there are patients that have been given completely cultured bladders with assistance from doctors that have applied nano biology in their practices. Although not yet perfected for humans, studies of animals have resulted in uteruses grown outside the body and placed into animals, which have then given birth to offspring. That’s amazing! The hopeful health possibilities for those with diseased organs are exciting. Researchers are also studying the potential future practice of providing new limbs to patients, as an alternative to only providing prosthesis. Another promising area of study involves developing polymers that can detect various metabolites. The goal for this study is to one day introduce these polymer particles into the human body so they can find metabolites linked with tumors and other health issues. They’re like nature’s little internal detectives, if you want to look at them that way.

One of the big nano biotechnological goals is to create molecular machines, if you will, which imitate organisms that exist in nature. For instance, Dr. Gunther Gross at the University of North Texas found in his research that colonies of live neurons can live together on a bio chip device.

In order to apply nanotechnology to biological aims, specialized instruments, called nano tools, must also be developed. Such tools are many times made to refine applications of nano tools already in use. One good example of nano tools is the use of nano particles for delivery systems or sensors.

DNA nanotechnology is also a fascinating application of bio nanotechnology. One such application for it is utilization of the natural properties of nucleic acids, such as DNA, to create useful materials. Another big research topic in this area of study is using membrane properties to generate synthetic membranes.

The future of nano biotechnology is both exciting and scary, at the same time. For instance, the biochemist Clyde Hutchison has said that the synthetic organisms, which can be created and manipulated using this technology, would give humans much more control over the properties of cells. So, what does he mean by this? Well, for one thing, humans would be in a much better position to design exactly what they really want. That’s a good thing if you strive to eliminate diseases in humans. However, some might look at it as humans trying to play God. After all, if God created humans in the first place, wouldn’t His creations then be messing with His original design? No matter what side you come out on these big questions, this a fascinating field of study. And it’s one that will be raising many interesting and debatable questions for many years to come.
