Important Data on Nanoparticles
- Silver nanoparticles are used in making medical equipment, textiles, and cosmetics taking advantage of their antifungal and antibacterial properties.
- 3-D printers emit nanoparticles that may be harmful to sensitive people with higher concentrations that are dependent on the types of filaments used in the printing process.
Nanoparticles Types, Production and Uses
As the name suggests, nanoparticles are very small size particles. The size of nanoparticles is in the range of 1 -100 nanometers. So any particles below 100 nm in size can be termed nanoparticles. These particles are found to be composed of a few hundred atoms. These small-sized particles of any material possess some distinct properties and qualities that are significantly different from the bulk material. Due to the very small size, the ratio of surface area to volume is much more in the case of a nanoparticle. This feature attributes to some unique optical, chemical, and physical properties. For example, particles of a metal having size less than 50 nm have different performance in terms of ductility as compared to the larger size of the same metal.
