Enzyme sensors for environmental analysis

Biosensors are occasionally used to monitor pollutants in aquatic environment such as river or drinking water. Numerous important biosensors using enzymes have been fabricated for environmental monitoring purposes. Since immobilization of biomaterials such as enzymes are very important in the fabrication of biosensors for environmental monitoring, many intelligent materials such as photorosslinking polymers have been developed recently. This review introduces several immobilization materials and enzyme sensors for environmental monitoring (e.g. phosphate sensors).
