【Abstract】 Early developments of biosensors are retrospect briefly. Biosensors for environmental controlling have been developed either as broad-spectrum devices, such as for measurement of biochemical oxygen demand in industrial effluents and other waste water or for analyte-specific determination of pesticides, groups of pesticides, heavy metals, nitrate, nitrite, nitrilotriacetic acid,or herbicides. Many examples of biosensors (i.e. enzyme sensors, whole-cell biosensors, receptor-based biosensors and immunosensors) applied to environmental analysis are presented with their advantages and disadvantages discussed here. Also, the problems to be resolved immediately of biosensor research in environmental analysis are pointed out to serve as a starting point for information about trends and to encourage more research in this interdisciplinary field.更多还原
