Application of nanotechnology in the environment biotechnology

Abstract

With the increasing industrialization and urbanization, the environment is getting polluted. Conventional techniques such as filtration, centrifugation and biological treatment are expensive and not efficient one. Therefore, there is a need for the development of recent and efficient techniques for environmental monitoring and treatment. Nanotechnology is the solution to the abovesaid problems. Nanoparticles, nanomembranes, nanofilters, and nanocatalysts have been developed for wastewater treatment. These have smaller size (1-100 nm) and higher surface area to volume ratio. Due to these properties, they provide more reaction surface which results in increased efficiency and selectivity. With the some issues solved, nanotechnology will answer all the environmental problems.
