Fig. 6. Raman spectra of MGAuNS@B after competition with (a) mannosidase, (c) neuraminidase or (e) N-acetyl-glucosaminidase-treated cells of different concentrations. Plots of Raman peak intensity at 714.3 cm–1, 1187.4 cm–1 and 1324.2 cm–1 vs. (b) mannosidase, (d) neuraminidase and (f) N-acetyl-glucosaminidase-treated cell concentration.
