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 ...

Biosensors and Bioelectronics, 2002
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.

Current Opinion in Biotechnology, 1996
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.

Gravimetric transducers produce a signal based on a change in mass. These transducers can be used to construct gas sensors or biosensors using odorant binding proteins (OBPs) as recognition elements for small volatile organic compounds. The methods described in this chapter are based on the immobilization of the OBPs onto functionalized (activated ...

Methods, 2005
Biosensors are sensors in which biomolecular interactions are used as sensing reactions. Biomolecular interactions, when combined with a microcantilever platform, can produce an extremely powerful biosensing design. The resonance frequency of a microcantilever shifts sensitively due to mass loading from molecular interaction as in the case of any ...
