Particles of very small size (Nano size) have their own unique characteristics. They act differently from macro particles because of their minuscule size. This attribute of the Nano-particles are used in various fields of science, technology, bio-medics. They have a set of physical and chemical attributes which make them the particles of the future. In contemporary times the Nano-particles have applications in sunscreen, chemical catalysts and antibacterial agents, creating lifesaving drugs.
