Nanosensors: Applications and Challenges

Asim Kumar

Abstract: This paper discusses nanosensor developments and applications. It illustrates progress in environmental field by considering a number of applications of nanosensors and their products. This paper shows that the innovative biosensors, gas and chemical sensors are having a growing impact in the present scenario. Many of the US?based companies have frequently raised significant finance and subsequent funds from government agencies involved with defence, homeland security and healthcare. Many of the world's largest, high?technology companies are pursuing nanosensor developments. This paper briefly discusses nanosensor applications and provides an insight into the present day state of nanosensor commercialization.
