โฆ Synopsis
Advances in biosensor technology over the past year have included developments in metalized electrodes, mediated electrochemistry, direct electron transfer, impedance measurement, optical immunosensors, optodes, biomimicry, piezoelectric biosensors, enzyme thermistors, in vivo biosensors, surface characterization, organic-phase biosensors and tissue-based biosensors. Increasingly, molecular biology and engineering are being used in sensor design.

Work on a new type of biosensor, in which changes in the dielectric properties of an electrode surface are detected, started during the late 80s. The binding of an analyte to an immobilized afยฎnity element can be detected directly without the need for a label or an indicating reaction. The changes c
