A biosensor is an electrical device encompassing biological components, with the intent to detect and measure the concentration of the analyte in a sample. The applications of the biosensor are numerous including, but not limited to food, healthcare and environmental sectors. In particular, biosensors based on enzymatic inhibition are highly sensitive in monitoring the inhibitory analytes affecting the catalytic activity of enzymes. A careful selection of transducer, a biosensor component for transforming the biochemical signal to an electrical signal along with the choice of enzymes is crucial in determining the commercial viability of enzymatic inhibitory biosensor. This chapter highlights the recent studies as well as products available in the market related to biosensors based on enzymatic inhibition. Besides, the economic analysis of existing and futuristic biosensors is also discussed.
