Biosensors

Journal of Chromatography A, 1990
This review introduces biosensors as analytical devices that respond selectively to analytes in appropriate samples and convert their concentrations into electrical signals via a combination of a biological recognition system and a suitable transducer.

Impedimetric Biosensors

Journal of Bioscience and Bioengineering, 2004
Electrochemical impedance spectroscopy (EIS) is a sensitive indicator of a wide variety of chemical and physical properties. An increasing trend towards the development of impedimetric biosensors is being currently observed. Impedimetric techniques have been performed to characterize the fabrication of the biosensors and to monitor the catalyzed ...

Electrochemical biosensors

Chemical Society Reviews, 2010
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 ...

Biosensors

Journal of Physics E: Scientific Instruments, 1984
This paper will commence with a general introduction to the concepts and technology of biosensors including some discussion of the need for sensors, the range of analytes that can be measured, the areas of application, the construction of sensors with a biological recognition/response system and the range of transducer technologies that are potentially
