Electroanalytical Chemistry, and specifically the design development and application of direct and selective chemical sensors and biosensors in environmental, clinical and food samples.
The ionic and mainly the anionic chemical recognition schemes using synthetic novel organic and organometallic compounds are the prime interests of the chemical sensor section. In the area of biosensors we focus our efforts in the development of novel matrices additives and mediators for increasing the operational and storage stability of these systems, improving the sensor to sensor reproducibility, and optimizing the overall analytical characteristics of these systems for real sample analyses.
The applied research section of the laboratory undertakes projects related to the development of analytical instrumentation for specific applications (F.I.A., I.S.Es, Optodes), as well as method optimization and application in chromatography (PCD) etc.
