Some new aspects in biosensors.

This paper reviews recent advances in biosensors contributed mainly by our laboratory. The biosensors, based on the new immobilization materials - sol-gel organic-inorganic hybrid materials, cryohydrogel (or organohydrogel) and bilayer lipid membranes, are presented. The analytical performances of the biosensors are discussed. Applications of the biosensors in extreme environment are emphasized. A new generation of biosensors - surface plasmon resonance biosensors and capacitance biosensors, are also described.
