Abstract
About this talk
Nanosensors are one type of sensors. Others include bio-sensors, catalytic sensors, electrochemical sensors etc. Nanosensors are nanoscale devices that are constructed to identify a particular molecule, biological, medicinal or environmental component and operate within the nanoscale dimensions. Nanosensors convert chemical data such as the concentration of a single sample component to complete composition analysis into an analytically usuable signal. Nanosensors are quite superior to conventional sensor and possess several advantages over conventional sensors. These include amongst others: greater adsorptive capacity due to large surface area to volume ratio, greater modulation of electrical properties such as capacitance, resistance etc. upon exposure to analytes, exceptional electrical conductivity and compatibility with biological systems. Nanosensors have found applications in several realms such as agriculture, biology, chemistry, physics, medicines, environmental, gas sensing, industrially, in the aerospace and defence industry. Research in nano sensor technology is proliferating.
