ABSTRACT

Nanotechnology has massive capability in several areas and is developed as a technology to direct the way on the way to sustainable progress in the approaching years. The indispensable subject of nanotechnology is to use particles of nanometer dimensions. In this chapter, we throw light on the basic concept of nanotechnology. This chapter answers the questions like: Who is the father of Nanotechnology? How it is developed? Gigantic spotlight on nanotechnology in past decades have led to its open expansion and thus vast use of nanoparticles (NPs). Along with this we discussed in this chapter about how many types of nanomaterials are there? This chapter also deals with how nanotechnology affects human life in both ways: positive and negative in various fields like health, environmental, social, and economic fields. Some measures are also discussed by which this technology can be used more effectively with minimum negative effect.
