Nanosensors To Detect Environmental Pollutants

Saranya S Kumar

Abstract

Nanoscience and nanotechnology are fields of study of matter in the nanometer scale in which the quantum and surface effect provide wide range of properties. Nanoscience explores the fundamental principles for its special properties. On the other hand, nanotechnology applies this knowledge for developing new devices, materials, and systems with enhanced performance and functions. Environmental applications of nanotechnology are one of the many outstanding utilizations of nanoscience. Commonly used devices are water purifiers, air filters, solar cells, pollution sensors, etc.Advances in various industries release toxic pollutants to the environments which affects the earth in various ways. The air we breathe, the water that holds the existence of entire life are suffering pollution.Early detection and removal of these poisonous chemicals is of urgent priority. Nanosensors, which are under research and development, find many applications, among which is the mission of filtering theentire life system is appreciable. This review concentrates on nanosensors to detect environmentalpollutants in order to safeguard human health, promote environment sustainability, and protect our ecosystem from the harmful effect of unbalanced physical surroundings and ecology. High sensitivity,miniaturization, real-time and rapid response, versatility to detect pollutants in gas, liquid, or solid form are the reasons that attract many researchers towards the development of sensors in nanometer range.
