Nanotechnology is the most emerging science nowadays, which is becoming quite popular. Besides a number of nanotechnology applications, it has also given us some of the very useful products. Nanotechnology is included in most of the products such as sunscreen, solar panels, various devices, etc. Nanotechnology devices have a huge market, and the research and studies are regularly funded by potential organizations.
Cost effective nanodevices
Some of the research centres are trying to make the nanodevices much more economical without compromising on the quality. MIT's Microsystems Technologies Laboratories have made a MEMS- based sensor, which is equally good as the commercial sensors. Additionally, the major components of desktop fabrication device can be easily built with the help of 3-D printer. In short, the nano devices can be made using just one-hundredth the cost of what was required earlier.
"The additive manufacturing we're doing is based on low temperature and no vacuum. The highest temperature we've used is probably 60 degrees Celsius. In a chip, you probably need to grow oxide, which grows at around 1,000 degrees Celsius. And in many cases the reactors require these high vacuums to prevent contamination. We also make the devices very quickly. The devices we reported are made in a matter of hours from beginning to end," said Luis Fernando Velásquez-García, research assistant at the MIT Microsystems Technology Laboratories. Also by using the 3-D printer, it becomes easy to build devices fit to serve specific functions.
Laser printing technology
Another amazing nanotechnology application is the laser printing technology, which allows one to print high-resolution photos, with great quality. By using this technology researcher from DTU nanotech and DTU Fotonik have successfully created a microscopic colour image of Mona Lisa, which is less than one pixel. Laser printing technique done with the help of nanotechnology can produce brilliant images of 127,000 DPI resolutions compared to the normal 300 DPI resolution of normal prints.
The team of researchers firmly believes that the new technology has a wide scope of commercialization. For example through laser printing, one can print things, which cannot be seen with naked eyes. Hence, if invisible prints are applied on various products it will help to determine the originality of the products later. In addition, it will fight fraud and forgery. Another use of laser technology is personifying products such as printing names or designs on personal gadgets. Foreign companies are taking special interest in this nanotechnology application to print car designs, and expensive personalized gifts.

Nanostructured window coatings
Indoor air, which remains compact inside the house, can cause harmful diseases to the inhabitants of the house. The problem is also referred to as “sick building syndrome.” Cleaning the air requires energy and requires an expensive procedure to follow. On the other side, the researchers at Uppsala University using nanotechnology have developed a new technique. This technology uses nanostructured coating of titanium dioxide on the window glass pane; it uses sunlight to remove polluting agents by passing the air between the window panels.
Titanium dioxide is a white pigment used in various different products such as paints, sunscreens, etc. It contain some properties, which keeps it highly reactive, it uses the energy of ultra violet rays, which it absorbs from the sun. This energy is then used to kill the organic germs present in the air. The process is called photocatalysis.
Titanium is often referred as the “white knight” in the field of nanotechnology. Researchers have used the industrial process called “magnetron sputtering,” to deposit nanostructured titanium dioxide at the windowpanes. The coating is transparent and has a diameter of less than 100 times a human hair, the technology is said to be very effective in removing indoor air pollutants.Tag(s) : Nanoscience, nanotechnology, nano materials, nano particles,
