Nanoparticles Can Help Prevent Colds.

During the flu season, many people are busy going to hospitals for vaccination or taking vitamin boosting immunity. If there is a "magic coat" that can help people "catch" and isolate influenza viruses in the air, so that you are not afraid of catching a cold, how good it is! T-shirt It's good to filter toxic fumes, so that you can breathe clean air. It's best to keep these clothes free from ironing and to save time and trouble.

According to the American Journal of popular science, all this is not an Arabian tale. clothes It has already appeared. Recently, at a fashion show held at Cornell University, researchers showed this kind of coat and skirt with metallic color to the outside world.

First made Using nanoparticle cloth

This fabric has successfully attracted the attention of garment manufacturers, researchers and even military laboratories. Its "shining point" is not its avantgarde fashion, but its germ control ability. It looks like it is made of ordinary cotton, but a nanoparticle is added to its fabric to detect and "catch" viruses and germs floating in the air. The pads, sleeves and pockets of clothing also have unique palladium particles, which are similar to miniature exhaust purifiers and can be used to decompose harmful air pollutants.

The "magic coat" designed by Olivia Von, the designer of Cornell University, used the real nano particle cloth for the first time. The fabric contained many nanoparticles with diameters less than 100 nanometers (1 nanometers 1/1000000000 meters), and the diameter of particles was only 1/1000 of the thickness of cloth.

In order to develop this kind of nanoparticle cloth, Olivia asked for help from Hu An Inestrosa, a specialist in fiber science and chemical engineering at Cornell University. Inestrosa inserted metal ions into cotton by electrostatic action. Inestrosa said that the use of metal particles designed personal air purification system, for example, silver has natural antibacterial function, far smaller than the diameter of the nano silver particles, can be attached to clothing, and can eliminate viruses or bacteria.

Because nanoparticles are very small, users need not worry about the comfort of cloth. In addition, nanoparticles also prevent large particles from sticking to the surface of clothing, so this "magic coat" does not need to be cleaned frequently.
