Abstract
Chemical microsensors based on ion sensitive glassy membranes. Thick a nd thin films of chalcogenide glasses can be used to build up sensitiv e microsystems able to detect ionic species (Hg2+, Cu2+) in aqueous so lution. Characteristics of sensing systems based on thick or thin film s elaborated by the fast quenching method or by vacuum evaporation are presented. Regarding the detection of Hg2+ ion, the microsensor exhib its a very low limit of detection close to 10(-8) mol/l. A quasi-Nerns tian behaviour over six orders of magnitude and a very good stability are observed on the Cu2+ ion sensing system.
