2968-2973Disposable electrochemical sensors and biosensors
applied to the environmental and food analysis are presented. For this purpose screen-printed
electrochemical transducers, produced by thick-film technology, have been
modified in order to get the specificity of the devices for their target. The sensors
are coupled with fast and sensitive electroanalytical techniques
such as differential pulse voltammetry
(DPV), square wave voltammetry (SWV), chronopotentiometry at constant current, or
chronoamperometry to obtain accurate results in a few minutes. Applications to
heavy metal, DNA damage and polychlorinated biphenyls (PCB) detection have been
reported
