The BMBF-funded project »GraphPOC« is working towards a point-of-care diagnostic platform based on graphene technology. The ambition of the project is to design a purely electrical system that can recognize certain biomarkers in human blood and distinguish between bacterial, viral, or fungal infections. The concept developed in cooperation with the Technical University of Berlin relies on the high-precision deposition of organic, reduced graphene oxide, its biological application by means of catcher molecules, and the embedding of sensors in a disposable package, using microfluidics and RDL. The system has the potential for use with other biomarkers in the future as well.
