Introduction to Nanoparticles: Size, Properties, and Applications

The video discusses nanoparticles, which range from 1 to 100 nanometers in size, and their unique properties due to high surface area to volume ratios. It explains how these properties affect their chemical and physical behavior, using a cube to illustrate the concept. The video highlights potential applications in medicine and industry, such as drug delivery and catalysis, while also addressing safety concerns like flammability and health risks associated with inhalation.
