The application study of biosensors in environmental monitoring

Environmental monitoring is the premise of pollution, and it provides scientific basis for environmental management and protection. Based on its advantage of on-line monitoring, biosensor is paid more and more extensive attention in environmental monitoring. This paper summarizes the basic principle, characteristics and types of biosensors. The detecting methods and evolution of biosensors are analyzed about in environmental monitoring, especially emphasizes their application in the monitoring of water and atmosphere. The development tendency and prospect of environmental biosensors in the future are predicted as well.
