“Nano Technology”, the hottest topic in today’s era in Science Field. There are lots of developments and Innovations in the field of Nano Technology that too at a rapid pace! So let’s Discuss about it.

So let’s understand the matter at Nano scale, because Nano particles have become a huge part of our lives.
If we look at the basic definition of Nano technology, then Nano technology is the manipulation of matter or functional systems at the supra molecular, molecular and atomic level. National Nanotechnology initiative gave a much generalized description of nanotechnology. It states that, it is the manipulation of matter, at least the dimension should be sized from 1 to 100 nanometers. Nano Technology covers both the present work and the concepts that are very advanced. It is the concept of constructing items from the bottom up by using tools and techniques used today to make high performance products.
The concept is very broad and it is defined by size. It is studied in many areas such as Molecular biology, organic chemistry, micro fabrication, semiconductor physics, surface science, etc. The research and applications are very diverse, from developing materials on nano scale to directly control of matter on atomic scale
The theory states that that quantum mechanical effects are so vital at quantum realm scale. It has many potential applications like in the military and the industrial areas. For the nanotechnology research Government is investing billions of dollars. For example through National Nanotechnology initiative, until 2012 European Union invested 1.2 billion, Japan had invested 750 million dollars and United States of America 3.7 billion dollars.
Conducting electricity from nano particle-filled ink:
Researchers are working on how to make conductive ink from silver nano particles and how that filled ink would conduct electricity. Nano particles have great viscosity when they are suspended in cellulose solution. A line drawing would become a silver wire that can carry current. The current is enough to power a small LED display (or Light bulb) or an antenna. So this is something amazing.
For many new sniffers of cancer and other diseases, Gold nano particles are been used. Researchers are working on gold nano particle sensor that would not only tell whether the person is suffering from cancer or not, it will also tell the kind of cancer the person suffering from, whether it is colon or prostate, breast, lung cancer. The advantage of this system is early warning capability.
Chad Mirkin, a researcher is working on nano particles that can diagnose disease, it can also track cancer at the earlier stages and it would also tell whether hospital patients have infections or not. Nano particles has all the answers to plenty of potentially dangerous questions. Mirkin is also working on sepsis, gold nano particles with DNA can now identify whether someone has sepsis or not. Mirkin said that there is a huge difference between a $20 test and thousands of dollars in antibiotics.
Osorb can quickly demonstrate the strange behavior of nano particles. Researchers are working on nano structured silica. They discovered a formulation in which they were assembling nano particles into porous glass film became flexible. Instead of getting solidified, they had the ability to swell, the researchers saw a color change but it soaked entire volume of test solution. With more test solution, it just got expanded. The material had some interesting properties. It did not react with water. Molecules can get through the Nano size silica but water was not able to pass through. So this useful for water cleanup. It can clean the oil stains. Osorb is been used at many places such as parking lots where it helps in absorbing oil form leaky cars. Researchers are now working on new project that how it can be decorated with other materials to capture chemicals like phosphate.
Combating cancer at the source:
Researchers are trying to find out that whether gold nano particles are safe or not. They did their research on a dog who had prostate cancer. Dog underwent CT scan to determine the size of tumors and a liquid containing radioactive gold nano particles was injected. The dog showed no toxicity or swelling or any kind of change in kidney and liver. So radioactive gold nano particle has the potential to help human men in future. Researchers have also built degradable nano particles.
Nature Nano Technology:
Well we know that nano fibers are used in many areas from tennis rackets to aircraft wings. But inhaling airborne nano fibers and nano particles can lead to many pulmonary diseases like fibrosis.
A study was done that a mice consuming nano-titanium dioxide showed DNA damage, it can cause neurological disease, cancer, aging and heart disease.
Now the researchers are focusing on Nature nanotechnology. According to them some forms of carbon nano tubes, if inhaled could be harmful. Some of them can cause mesothelioma, so those should be handled carefully.
Proactive coating for your skin:
Many don’t know but sunscreen also contains nano particles of zinc oxide and titanium dioxide which can prevent people from penetration of harmful solar radiation. A recent study in UK showed that titanium dioxide do not penetrate the top layer of skin but still can do harm.
