Application of Nanotechnology for Environmental Problem

Due to extensive human economic activities and their population growth, Environment of our planet is rapidly losing its quality in its every part (air water, soil, forest etc). The air and water parts are the easily affected entities of our environment. Use of non-renewable energy for manufacturing, transportation, home etc is directly related with environmental pollution. To reverse these negative effects on the environment, many attempts have been made so far by using different approaches, although the problem is still on the rise. The approach by nanotechnology is highly promised because of the unique properties of nanomaterials. This technology has already shown the potential to treat our environment including air and water purification, solving energy crisis, protecting our skin from skin cancer, increasing agricultural production etc. In this review paper, the application of nanotechnology in air and water purification, in energy sector and in the production of sunscreen lotion and its use for skin to protect our skin from strong sun radiation have been reviewed.
