Abstract:
The impetuous development of sensors boosted current technologies to unsuspected limits and performance. The high-technology sensory structures help us to obtain information in real time about things that we can smell, touch, hear and other things that we cannot detect. Sensors are devices which convert physical, chemical or biological changes into processable and quantifiable electrical / analytically signal. Electrochemical sensors, accepted and employed, have been developed to increase the surface area of electrode, to enhance oxidation signals.
An increase in the number of applications for biosensors developed or being developed has ensured that this technology follows a growth curve, leading to standardization in the areas of drug discovery, biodefense, environmental monitoring and detection of different toxic substances.
The continual research and development efforts being undertaken would go a long way in making sure that biosensors technology would continue to evolve with faster, more specific and high specialty applications.
Due to physics it can facilitate the understanding of certain phenomena found in different areas and may provide new methods for analysis and synthesis of the product. If the researches in physics from the past focused not so much on the development of biosensors, now, in present, their attention is given based on electrochemical, optical, piezoelectric and thermometers methods.
