Preliminary Investigations on Immunosensorsfor the Gasphase

Abstract

The Dragerwerk AGis selling chemical tests for gas phase measurements which are quick and easy to handle. Today government laws and the market demand more specific and more sensitive tests. Using enzymes Drager enteredthe field of biosensors by developing a highly sensitive and highly specific formaldehyde biosensor (1). This sensor allows analysis through simple color comparison. But lots of substances cannot be measured by using either enzymes or chemicals. Amongthem areinsecticides like pyrethroids and bacteria like Escherichia coli K-12. Therefore we started to develop tests based on immunological reactions.
