Biosensors for Clinical Diagnostics

Biosensors are defined as a combination of a physico-chemical transducer which detects a signal generated by the reaction of the analyte with a biological recognition molecule. Biosensors were first developed in the 1960's [1]. Developments were mainly driven by the desire to provide a better glucose measurement for diabetes monitoring. The new technology is now used in approximately 7% of those applications. Biosensor products were also commercialized by companies offering blood gas and blood electrolytes analyzers, integrating glucose, lactate and other biosensors into these systems to allow fast measurement i…
