Abstract

This chapter provides a brief overview of the literature on sensors and bioassays using cyclodextrins, the special carbohydrate molecules which form inclusion complexes with various organic chemicals. They can be applied in risk assessment and monitoring in various ways: i) Cyclodextrin derivatives bearing a chromophore/fluorophore moiety are especially selective and sensitive as sensors due to their changed fluorescence spectrum in the presence of an appropriate competitive contaminant. ii) The samplers containing cyclodextrin collect and concentrate the target contaminants from the contaminated phases of chemical analyses and bioassays. iii) Soil extraction with aqueous cyclodextrin solution has become an everyday method to predict the microbial bioavailability of organic contaminants. iv) In toxicity assays or bioassays cyclodextrins can sensitize or attenuate the effects depending on the conditions of the tests.
