Abstract
Bio-related reactions are
broadly applicable in detection and determination of specific substances
as well as in chemical synthesis. Many types of biosensors have been
developed by use of biomaterials, such as enzymes, antibodies and
binding proteins. In biosensing systems, it is essential to convert
chemical and/or physical changes accompanying specific molecular recognition
with the biomaterials into definite information. Bioelectrochemical
systems consisting of biochemical and electrochemical reactions are
promising candidates to inform the biochemical molecular recognition
as electrical signals. In this article are surveyed the molecular
recognition with biomaterials, their application to biosensors, especially
to bioelectrochemical sensors, and the example of amperometric sensing
with them.
