Abstract
Thin films are used in every domain of biosensor systems as for sample handling, biological recognition and amplification, transduction and electronic signal processing. Several planar microelectrochemical chips with thin-film electrodes of different shapes and arrangements on Si or glass substrates have been developed and utilized in voltammetric and potentiometric sensors. Bilayer lipid membranes (BLMs) are very ‘‘adaptive’’ thin-film materials applicable in biosensors. Forming of BLMs on planar chip with thin-film electrodes has opened up new possibilities for the development of miniaturized biosensors as well as for basic research on electrical and mechanical properties of biological membranes.
