TechPat nano

Functional lateral flow arrays for the identification of multi-resistant pathogens

Scientists at the IPM within the “TechPat nano” project are involved in technological system development to prepare the next generation of near-patient diagnostics. A therapy-accompanying, non-invasive monitoring test after kidney transplantation is being developed. This test is designed to enable early detection of transplant rejection and functions by determining the molecular marker “kynurenine”, a degradation product of the amino acid tryptophan. In this way, the test enables immunosuppressants to be adjusted in a course-specific manner and thus offers the patient a high level of added value and safety.

The single molecule analysis of kynurenine will be performed using nanopore biosensors – for which the synthesis and characterization of corresponding kynurenine-competitor conjugates is being carried out at the Institute of Precision Medicine. Enzyme-based approaches for the detection of kynurenine are also being developed. Furthermore, an LC-MS based reference method for the quantification of kynurenine in real samples is developed and applied to corresponding real samples. The scientists also undertake the synthesis of functional acrylate-based monomers for the production of polymer membranes.
