Abstract
A review is provided dealing with the definitions and classifications of biosensors, as well as their basic working principles. Then, their applications to the environmental monitoring, which include the monitor of biochemical oxygen demand (BOD), bacterial count and various organic and inorganic pollutants, e.g. nitrogen compounds, heavy metal ions, organophosphorus pesticides, phenolic compounds, toxic compounds, carcinogens, teratogens, benzenes, sulfur dioxide, aldehydes and ethanols are presented. In the end, some suggestions were given with respect to the current problems of biosensors and the future applications of biosensors were also discussed.
