Laboratory of electrochemistry

The main aim of this research group is to focused on the sensors and biosensors frabrication for detection and monitoring of biological substances. Moreover our research interest is focused on the methylated DNA by electrochemical impedance spectroscopy. In addition we are able to detect various cancer proteins or markers. We coolaborate with a research group of molecular biology that focuses on platinum cytostatics determination. Another area of interest is electrochemical detection of heavy metals, focusing on environmental protection (detection of heavy metals in waste water).
