Exploring the potential of nanosensors: A brief overview

Nanosensors are now being used to detect and monitor physical characteristics such as the temperature at nanoscale, with chemical species and nanoparticles. It is nanoscale devices that monitor and transform physical quantities into signals that are detectable and analysable. Nanosensors are used in medical, pollutant control, pathogens detection, monitoring processes of manufacturing and transportation systems. This technology can identify specific cells at the molecular level to deliver medicine and monitor the development of particular places in the body by measuring physical characteristics such as volume, concentration, movement and speed, gravitational, electric, magnetic forces, pressure, temperature, etc. This paper briefly discusses nanosensors and their associated varieties and their sensing techniques, along with advancements. Taxonomy of nanosensors for industrial perspectives and associated recognition elements are discussed diagrammatically. Furthermore, ten significant potentials of nanosensors are identified and discussed. Therefore, the present review work may be a basis for future research work to find a consolidated report on the potential of various nanosensors.
