Trends and Perspectives in Immunosensors [PDF]
, 2012 Immunosensors are devices that comprise both a biomolecular recognition system, such as an antibody and its corresponding antigen, and a transducer to translate the high affinity and specific binding event into a physical signal. Antibodies are produced by an immunological response to the presence of a foreign substance called an antigen.
