Outlooks of Nanosensors in Medical and Smart Devices, Agricultural and Food Technology

Abstract

Nanosensors are medical devices where nanostructures are usually employed to sense the chemicals, gases, bio-representatives, electric fields, light, heat, temperature, pH, humidity, etc., since nanomaterials extensively enhance the compassion of the technique. Nano-biosensors utilize the bio element as an indicative constituent and the electrode as a transducer. Nanostructures are used in the system to bridge the space between the converter and bio receptor at a nanoscale. Several nanostructures like nanoparticles, nanotubes and nanowires, nanofibers, nano-pores, self-adhesive mono layers, and nanocomposites are employed to enhance the efficacy and competence of the biosensor device. Recent developments in nanotechnology further enable this field to prepare cost-effective, rapid, efficient, real-time, portable, robust, and disposable sensors for various applications in many areas, including health care. This article reviews a variety of biosensors and biochips, highlighting the function of nanostructures prepared for medical diagnostics, agriculture, food, energy, innovative packaging, chemicals, and other applications.
