The aim of the research group “MultiHoloDiag” is to investigate multiparameter measurements of the interaction of biomolecules with optical-holographic methods for use in medical diagnostics. Detection units are used, which are based on holographic procedures and are also technologically suitable for diagnostic on-site use. The group develops solutions for preanalytics and for the label-free, highly sensitive detection of single layers of molecules. The systems are developed and tested using clinically relevant samples.
