Τhe aim of the project is to deliver innovative components for in situ detection of heavy metal ions in water and for presenting the analysis results in a concise yet inclusive manner. To address this aim, a novel microfluidic chip will be designed and developed that integrates functions of sensing, detecting and analyzing water samples. The heavy metals to be detected will be Cr(III), Cr(VI), Pb2+, Hg2+ and Cd2+; that are well known pollutants for the environment even at low concentrations. This microfluidic together with the high selectivity biosensing components will be integrated into a portable IoT hardware platform that communicates the collected data to a cloud infrastructure which in turn stores and presents the analysis results in a web environment.
