Characterization of the functionalized glycopeptide-CNO conjugate (Gly-CNO). (A) Thermogravimetric analysis of p-CNO (black), ox-CNO (blue), PEG-CNO (red), and Gly-CNO (green). All experiments were run in air with a temperature rate of 10 °C min−1. (B) Absorption spectra of Gly-CNO (solid line) and fluorescent labeled glycopeptide 1 (dotted line) in DMEM phenol red free at a concentration of 10 μg mL−1. (C) ATR-FTIR spectra of Gly-CNO using germanium crystals and 256 scans. (D) Emission spectra (λexc = 490 nm) of fluorescent labeled glycopeptide 1 (dotted line) and Gly-CNO (solid line) in DMEM at a concentration of 10 μg mL−1. (E) HR-TEM image of a portion of a cluster of Gly-CNOs, partly suspended on a hole in the carbon film.
