ANALYTICAL CHEMISTRY SEMINAR “OPTICAL METASURFACES FOR BIOCHEMICAL SENSING AND SPECTROSCOPY”

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. Therefore, they are not suitable for point-of-care and lab-on-a-chip applications. 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, first, I will give an overview on the plasmonic biosensors, introducing different optical interrogation scenarios including spectroscopy, intensity-based imaging and phase-based interferometric optics. In particular, I will present 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 ultrasensitive biomolecule detection and spectroscopy. Here, I will emphasize the importance of the hyperspectral imaging optics enabling the spatially resolved spectral data acquisition.
