A Review on Outlook on Future Prospects of Nanosensors

Indu Singh


Nanosensors are gaining increasing attention due to the need to detect and measure chemical and physical properties in difficult to reach biological and industrial systems that are in the nano-scale region. Nanosensors have superior properties over the existing techniques such as high-performance liquid chromatography or gas chromatography, because they can provide rapid, sensitive, simple and low-cost on field detection. Research and development in the nanosensor domain is driven by specific market or application requirements and societal concerns. As the sensor industry is highy fragmented, it is difficult to identify the nanosensing product that is likely to do well commercially in the immediate future. It is equally tricky to spot the sensor market segment that is likely to be most influenced by nanotechnology, as new opportunities are spawned on a daily basis. This Basic review surveys various nanosensors, which are categorized into three broad types: optical, electromagnetic and mechanical nanosensors. The sensing concepts and their corresponding advantages were discussed with the reference to their applications. Future prospects towards the development of selective, sensitive biosensing system were also discussed in this paper.
