Applications of Nanoparticles: A step towards a Green Environment

Nanotechnology has its wide applications in different fields of health, energy, electronics, environment, space exploration and transportation. Green means the use of plant products and green nanotechnology is the branch that utilizes the concept of green chemistry and green engineering. It reduces the use of energy and fuel by using renewable inputs and develops clean technologies in order to minimize health and environmental risks. These products, processes and applications save materials, energy and water thus contributing to the environment. Apart from the development of solar cells, biofuels and fuel cells, synthesis of nanoparticles using sunlight or by recycling the industrial waste to produce nanomaterials is also necessary. Thus, green nanotechnology encourages the substitution of existing products in order to develop new products. This article reviews the applications of nanoparticles with their green synthesis and emphasizes their use to make the environment clean and green.
