Immunosensors, which are basically integrated and miniaturized immunoassay systems, are advantageous in several ways. In addition to their high sensitivity, selectivity, simplicity, multi-analysis capability, and on line and real time detection abilities, they are both very small and relatively inexpensive instruments. The signal transducing system, a core technology in immunosensor manufacture, has been extensively studied, especially with regard to three primary categories; namely, electrochemical, optical, and mass sensitive transducers. This article addresses signal transducing technologies that have been developed in the past few years, and also discusses possible future major trends in signal transducers.
