摘要：Environmental safety is the key requirements of our well-being. Rapid urbanization andindustrialization have greatly contributed several pollutants such as heavy metals, inorganic and organiccompounds, pesticides, toxins, endocrine disrupting hormones, etc. to the environment. The presence ofsuch pollutants is becoming a major global challenge for environmental security and human health. Althoughregulatory bodies are trying to control such pollutants at the source of entry, but still requires an effectiveand integrated environmental management program. Therefore, beside to minimizing/reducing or eliminatingthe amounts of hazardous effluents into the environment, there is an emergent need to methods that candetect and monitor these environmental pollutants in sensitive and selective manner to enable effectiveremediation. Application of modern nanotechnology based biosensors has a great potential forenvironmental surveillance and detection of pollutants. Such biodevices are portable and give rapidresponses in real time. In this paper, the author has discussed the key concepts behind the development ofbiosensor and explored the most relevant applications in the area of environmental monitoring. In addition,the author has also reviewed new developments, challenges in the development of biosensor along withfuture research direction in biosensing technology for sustainable environment monitoring.
