Nanoparticles - A Comprehensive Over-View

Nanoparticles are tiny particles the size range from 1 to 100nm.These are mostly made up of metal oxides, organic matter & carbon metal. They have different & unique physical & chemical properties. These are mainly Consist of complex structures, composed of 2-3 layers. These are variously used in different sectors. Pharmaceutical industries such as cosmetics, drug delivery system. Classified into organic, Inorganic & carbon based. These Nanotechnology is firstly discovered in 21st century. Mostly used in all industries since these are microscopic in nature. These are having various sizes and shapes. They had wide variety of applications in science, medicine & technology. Nanoparticles can be prepared by using various methods such as photo reduction, chemical reduction, solvothermal synthesis &spray drying. These are composed of natural or artificial polymers. Nanoparticles are not visible to our naked eyes. This review explains about nanoparticles it’s classification, properties, synthesis & their applications.
