Imaging-based molecular barcoding with Mid-IR dielectric metasurfaces
Mid-IR absorption spectroscopy is a benchmark method for bioanalytics and diagnostics, as it provides exquisite biochemical information of biomolecules. However, retrieving Mid-IR absorption signatures still requires complex spectroscopic techniques, severely hindering its on-chip integration for a wide range of analytical, industrial and field-deployed applications. In this talk, Prof. Altug from EPFL will introduce a wide-field imaging-based nanophotonic method that is capable of detecting and analyzing molecules with high precision and without needing bulky equipment. The method which uses all-dielectric metasurfaces opens the door to large-scale, image-based detection of materials aided by artificial intelligence.
