The aim of the GraphSens research group is to establish a robust, cost-effective and sustainable material platform for sensors to monitor environmentally relevant pollutants in water bodies or water treatment plants. This is made possible by combining ultrasensitive FET sensors made of CVD graphene (GFET) and graphene impedance sensors (GIS) made of chemically exfoliated graphene. The specificity of the sensors is realized by innovative functionalization of the sensor surfaces with "molecularly imprinted polymers" nanoparticles (MIP-NP). The surfaces functionalized in this way have high densities of adsorption sites for target molecules and provide regenerative capabilities during sensor operation.

The project on which these results are based was supported by the Free State of Thuringia under the number 2020 FGR 0051 co-financed by European Union funds within the framework of the European Social Fund (ESF).
