Metal nanoparticles overview
Metal nanoparticles (MNPs) are tiny particles made from metal atoms with dimensions in the range of 1 to 100 nanometers. These particles have unique physical, chemical, and electronic properties that differ from those of the bulk metal material. The surface area-to-volume ratio of metal nanoparticles is very high, which makes them highly reactive and can enhance their properties in certain applications such as electronics, catalysis, biomedical engineering, and materials science.
