Vikas A., Pundir C. S. Biosensors: Future analytical tools

 

Biosensors offer considerable promises for attaining the analytical information in a faster, simpler, and cheaper manner compared to conventional assays. Biosensing approach is rapidly advancing and applications ranging from metabolite, biological/chemical warfare agent, food pathogens, and adulterant detection to genetic screening and programmed drug delivery have been demonstrated. Innovative efforts, coupling micromachining and nanofabrication lead to even more powerful devices that would accelerate the realization of large-scale and routine screening, With gradual increase in commercialization, a wide range of new biosensors are thus expected to reach the market in the coming years.

Keywords: electrode, transducers, genetic screening, food analysis, bioterrorism, environment monitoring.
