Review of Biosensors for Environmental Field Monitoring

Environmental monitoring is one of the main priorities in Europe and in the world, due to the close relationship between human health and the environmental pollution. Biosensors offer generally cost-effective, quick and real-time analytical procedures for environmental monitoring. Due to technological development in last 10 years, this type of biosensors has been developed significantly as well. This paper is review of biosensors for environmental monitoring including water, air and specific soil pollutants (i.e. pesticides), specific toxic components and other micro organic molecules that are containing toxic chemicals in them. Different types of biorecognition elements and transducers, introduced to the public at the end of 20th century and at the beginning of 21st century, are mentioned and explained in this paper.
