Abstract: An impedimetric sensor for persistent toxic substances, including organic pollutants and toxic inorganic ions is presented. The persistent toxic substances are detected using an ultrasensitive technique that is based on electron-transfer blockage. This depends on the formation of guest-host complexes, hydrogen bonding, or a cyclodextrin (CD)-metal complex (M <subscript>m</subscript> (OH) <subscript>n</subscript> -β-CD) structure between the target pollutants and β-CD.
