Talk Title: Optical Metasurfaces for Label-free Biosensing and Bioimaging Applications”
Abstract: Mobile, affordable and reliable biochemical sensors that can drastically reduce the detection time by enabling multiple biomarker detection from small sample volumes are essential for effective next-generation healthcare. Unfortunately, current biosensing methods require laboratory infrastructure, trained personnel, complex and costly bioassay protocols. Nanophotonic biosensors can detect biomolecules in a label-free and non-destructive manner based on the enhanced light-matter interactions at nanoengineered surfaces. In this talk, I will give an overview on the nanophotonic biosensors particularly emphasizing miniaturized portable bioanalytical platforms that enable on-site applications, highlighting the results from a clinical study designed to detect Sepsis biomarkers from patient samples. Moreover, I will discuss the use of high-Q dielectric metasurfaces for hyperspectral biomolecule imaging.
