Abstract

Thin films in microelectrochemical biosensors can create sensoric interfaces, which are consisted of two main parts: thin film planar microelectrodes and active sensitive biological layers found on them. The quality of the sensoric interface is depending on quality of thin film electrode surface. Thin film electrodes have been cleaned by new pulsing cleaning. The model of the bilayer lipid membrane (BLM) consists of parallel RC circuit. The BLM formed on thin film electrode microsystems are described by a new equivalent circuit based on the standard BLM circuit. The mechanical properties of the BLM are included in variable membrane capacitance. This new models has been elaborated using a newly BLM simulator
