Development of Nanosensor for efficient Arsenic detection

Water is vital to the existence of all living organisms, but this valued resource is increasingly being threatened as human populations grow and demand more water of high quality for domestic purposes and economic activities. Among the various environmental challenges of that World is facing this century, fresh water scarcity ranks very high. The key challenges to better management of the water quality in global perspective and ind in Indian subcontinent are temporal and spatial variation of rainfall, improper management of surface runoff, uneven geographic distribution of surface water resources, persistent droughts, overuse of groundwater, and contamination, drainage, and salinization and water quality problems due to treated, partially treated, and untreated wastewater from urban settlements, industrial establishments, and run-off from the irrigation sector besides poor management of municipal solid waste and animal dung in rural areas. Being worldwide problem of Arsenic poisoning the present research work has been carried out to develop a detection kit that can detect Arsenic contamination in drinking water up to Nano level.
