Marker-free detection with photonic biosensors
Applications for medicine and health
Label-free detection methods - i.e. without additional reagents for molecular characterisation - have a high development potential as they can provide simpler diagnostic tools that can be used outside the laboratory and thus become accessible to non-specialist users. Fraunhofer IPMS is developing photonic label-free biosensors based on silicon nitride microring resonators in silicon technology. They are used for the selective detection of biomarkers or microbial substances and offer, for example, a suitable detection method for the early detection of diseases.
For this purpose, Fraunhofer IPMS, Fraunhofer IZI and Fraunhofer IOF are developing a highly sensitive integrated photonic biosensor platform at the Fraunhofer Center for Microelectronic and Optical Systems for Biomedicine MEOS in Erfurt.
