A Bioorthogonal Raman Reporter Strategy for SERS Detection of Glycans on Live Cells

Abstract

Direct detection of glycans on live cells using surface-enhanced Raman scattering (SERS) has been shown. A bioorthogonal Raman reporter was directly installed onto the monosaccharide analogs. Once metabolically incorporated into cell surface glycans, the Raman reporter was detected using SERS (see picture).
