The Laboratory of Analytical Chemistry is a basic and applied research facility specializing in the area of direct and in-vivo bio-chemical analysis. Emphasis is given to the design of chemical sensors and biosensors with analytical characteristics that allow for the direct, continuous and in-vivo bio-chemical analysis at trace levels. For this, organic and organometallic ionophores selective for anions and cations are designed and in conjunction with electroactive nanostructured transducers are employed as sensing elements. Electrochemical or optical biosensors are designed using either native or mutant catalytic proteins immobilized onto carbon nanostructures (nanotubes, nanofibers, nanocavities) or semiconductor quantum structures (Si, GaN, GaAs, InAs) in a planar of FET device arrangement. In addition the Laboratory is an applied analytical facility accredited to EN ISO 17025:2005 for food analysis.
