Abstract:
Amperometric biosensors fabricated by immobilizing enzyme colony in polymaleimidostyrene-modified micelles exhibited good sensitivity and great long-term stability. To our knowledge, there has not been a general design for various enzyme biosensors. Enzyme micelle membrane which is different from any of other conventional immobilization methods, is an innovative way and will be a well-developed biosensor technology to provide rapid and reliable measurements. The potential of using enzyme micelle membrane to fabricate biosensors will be of great hope.
