Introduction

Science and Technology of manipulating a matter to the level of atoms, molecules and supermolecules presents us with Nanotechnology. The new concepts of technology are spreading every day. So, we need to understand that technology has been and will be the most significant part of human society’s evolution and is unavoidable. But we should avoid the misuse and dangers of that technology. In the case of nanotechnology, the applications and inventions are expanding slowly, but steadily.

Solar cells, Bioremediation, clean technology, environmental microbiology, green chemistry and industrial microbiology are popular topics of nanotech subject. And now it has already applied to the industrial applications. Like: nano-foods, consumer goods like (sports items, textiles and cosmetics) and aerospace and vehicle. And also, Military (Biological sensors and weapons) and construction materials (cement and glass). Most of the researchers predict that, concerning about the human body and weaponry will be the two major areas to be developed in future.

Now let’s take a look at the latest inventions of nanotechnology.

Nano Bubble Water  

The Nano bulb water is developed by Japanese scientists. They displayed it during the Nano Tech Exhibition in Tokyo. And the inventors of this amazing invention are scientists of the National Institute of Advanced Industrial Science and Technology (AIST) and REO. This Nano Bubble Water allows both fresh-water fish and saltwater fish to live in the same water.

Nano sensor Probe

A “nano-needle” with a tip about 1000th size of a human hair pokes a living cell, causing it to quiver briefly. Once it is withdraw from the cell, this ORNL Nano sensor detects signs of early DNA damage that can lead to cancer. This high selectivity and high sensitivity Nano sensor was developed by a research group. It was led by Tuan Vo-Dinh and his coworkers Guy Griffin and Brian Cullum. The group believes that by using antibodies targeted to a wide variety of cell chemicals, the Nano Sensor can monitor in a living cell. (with the presence of proteins and other species of biomedical interest)

New Energy Source: Thermopower waves

MIT researchers have discovered a new energy source called Thermopower. Actually, they have discovered a previously unknown phenomenon that can cause powerful waves of energy. It can shoot through minuscule wires known as carbon nanotubes. This discovery could lead to a new way of producing electricity. The phenomenon, described as thermal power waves. MIT’s scientists, Michael Strano, Charles and Hilda Roddey have been said in 2011 that discovering a new area of energy research is very difficult and rare. But, however it has discovered and on the growing stage.

Carbon nanotubes are submicroscopic hollow tubes made of a lattice of carbon atoms. These tubes, just a few billionths of a nanometer in diameter, are part of a family of novel carbon molecules. It includes buckyballs and grapheme sheets. In a new experiment, the nanotubes were coated with a layer of a reactive fuel. It can produce heat by decomposing. This fuel ignited at one end of the nanotube using either a laser beam or a high voltage spark. And the result was a fast moving thermal wave traveling along the length of the carbon nanotube. It was like a flame speeding along the length of a lit fuse.

Results

Then, the heat from the fuel goes into the nanotube, where it travels thousands of time faster than in the fuel itself. As the heat feeds back to the fuel coating, a thermal wave is created that guided along the nanotube. With a temperature of 3000 kelvins, the ring of heat speeds along the tube 10,000 times faster than normal spread of this chemical reaction. The heating produced by that combustion, it turns out also pushes electrons along the tube creating a substantial electrical current.

The scanning tunneling microscope is widely used in both industrial and fundamental research to obtain atomic-scale or nanoscale images of metal surfaces.

Invented New Biomaterial

Catherine Hockmuth of UC San Diego reported that a new biomaterial designed for repairing human tissues do not wrinkle when it is stretched. The invention by the University of California marks a significant breakthrough in tissue engineering. As it more closely mimics the properties of native human tissue. Therefore, they hope that the future tissue patches, which are used to repair damaged heart walls, blood vessels and skin. With even more compatible patches.

This biofabrication technique uses light, precisely controlled mirrors and a computer projection system, shined on a solution of few cells and polymers, to build three dimensional scaffolds with well-defined patterns of any shape for tissue engineering.

Breathe giving inventions to health care

Nanotechnology is providing solutions for the chronic and fatal diseases like cancers, Parkinson, Alzheimer, diabetes, orthopedic problems, and illnesses related to blood, lungs, neurological and cardiovascular system. Therefore, the nanotechnology market size is expected to increase by 2025 with a huge amount. So, many scientists are working on the health related inventions combined with nanotechnology.

A Nanochip, is an example for the above mentioned inventions. It is fabricated to a living body as wearable. And also the Nanosensors, which is mentioned above. The black Silicon material that fights off bacteria, now found that it is potent enough against an array of gram – and gram + bacteria. (along with endospores)

Virtual Canvases

Nanotechnology will also provide the answer to the problem of heavily built-up sets by contact lenses. Bellevue, Innovega and iOptik like platforms provide a center filter and display lens at contact lens’s center. The optical elements are said to be smaller than the pupil’s eye. And do not hinder the normal vision.

Nano Absorption

Some graduates in Ohio, were trying to design nanostructured silica glass, to change colours in the presence of vapors. But in turn, they created ‘Osorb’; the swellable glass material. It resulted by changing the color, but it also soaked up the entire test solution. They added more solution to it, and it sucked it up too while generating an impressive amount of force. Therefore, by avoiding the mistakes, now, creating more energy efficient self-healing materials are under the lenses of researchers. It will be more beneficial for aircraft to electronics, obviating small fractures and more.
