▎ 摘　　要

Glycopolymers having three different pendant moieties, such as glucopyranoside, galactopyranoside, and mannopyranoside, were prepared and functionalized on the surfaces of nanoscale graphene oxide particles (GONPs). GONPs exhibited maximum absorbance at around 230 nm in the UV-vis spectrum with an average particle size of 200 nm as measured by dynamic light scattering measurements. The selectivity of pendant moieties of glycopolymer for binding with GONPs was assessed by fluorescence quenched in fluorescein isothiocyanate (FITC) conjugated GONPs. FITC interaction with GONPs led to a decrease in the fluorescence due to the resonance energy transfer and quantified the reappeared fluorescence of the FITC by glycopolymer co-functionalization with FITC-GONPs depending on the nature of pendant moieties and their respective concentrations. The binding of glycopolymers on GONPs was analyzed by Raman and UV-vis spectroscopic techniques. Glycopolymer chains with mannose pendant moieties exhibited the strongest binding affinity toward GONPs compared to the glycopolymer chains having galactose/glucose pendants.
