Lenses beyond limits: sculpting photons at the molecular scale for global health and sustainability (Hot Topics)

24 January 2022 • 5:25 PM - 5:45 PM PST | Room 207/215 (Level 2 South)

Abstract

We present a new platform for sensitive molecular detection and control spanning 1) multiplexed genetic and proteomic screening, 2) single-cellular bacterial identification and drug susceptibility testing, and 3) chiral molecular synthesis and separation, based on high-quality-factor phase gradient metasurfaces. The high-quality factor of our metasurfaces produces a large amplification of the electromagnetic field, increasing the response to targeted binding of biomarkers. Simultaneously, the optical signal is beam-steered for multiplexed detection. We develop these metasurfaces for a new respiratory panel of SARS-CoV-2, RSV, and influenza; Raman-based identification and antibiotic susceptibility testing of pathogens; and sensitive identification and purification of chiral molecules including amino acids and small-molecule pharmaceuticals and agrochemicals.
