Nanoparticle formation is a research area that focuses on the synthesis and characterization of nanoparticles, which are tiny particles with dimensions ranging from 1 to 100 nanometers. These nanoparticles can be made from various materials, such as metals, metal oxides, polymers, and semiconductor materials. Researchers in this field study the methods and techniques used to create nanoparticles, as well as their physical and chemical properties. The properties of nanoparticles make them useful in a wide range of applications, including drug delivery, imaging, catalysis, and electronics.
