Electrochemical biosensors combine the sensitivity of electroanalytical methods with the inherent bioselectivity of the biological component. The biological component in the sensor recognizes its analyte resulting in a catalytic or binding event that ultimately produces an electrical signal monitored by a transducer that is proportional to analyte ...

The biosensor field has grown enormously since the first demonstration of the biosensor concept by Leland C. Clark, Jr. in 1962. Today's biosensor market is dominated by glucose biosensors, mass-produced enzyme electrodes for the rapid self-diagnosis of blood glucose levels by diabetes sufferers. Here we take a historical look at the inception, growth,

Current Opinion in Chemical Biology, 1998
Current biosensor developments can be summarised by different trends. For traditional enzymatic biosensors such as glucose sensors, steady improvements of well known basic principles have been made in order to achieve better sensor stability. On the other hand, new affinity sensors such as nucleic acid sensors, transmembrane sensors, and sensors ...

Journal of Bioluminescence and Chemiluminescence, 1989
AbstractA novel optical biosensor for homogeneous immunoassay has been developed on the basis of the finding that electrochemical luminescence of pyrene‐labelled antigen is extremely inhibited by immunochemical complexation. Electrochemical luminescence homogeneous immunoassay for human serum albumin (HSA), as a model analyte, was performed with a ...

Direct electrode transfer between enzyme and the electrode in biosensors requires high efficiency therefore, synthetic replacement for oxygen led to the development of enzyme mediators and modified electrodes in biosensor fabrication. In this context, a number of electron acceptors and complexes have been used.

Over the past 18 months, our understanding of the chemistry and engineering principles of amperometric biosensors, including bioaffinity sensors, has deepened. In addition, several novel amperometric biosensors have been commercialized and progress has been made in the design of subcutaneous sensors, particularly those for glucose.
