Characterization of Ag-GQDs/DOX.

Notes: (A) UV-Vis absorption spectra of Ag-GQDs, DOX, and Ag-GQDs/DOX; (B) fluorescence of DOX (1 µM) is quenched by the increasing amount of Ag-GQDs from 25 to 200 µg/mL (i. 25, ii. 50, iii. 150, and iv. 200 µg/mL) in PBS buffer (pH 7.4). Excitation wavelength was 500 nm.

Abbreviations: Ag-GQDs/DOX, silver nanoparticles decorated with graphene quantum dots conjugated with doxorubicin; Ag-GQDs, silver nanoparticles decorated with graphene quantum dots; au, arbitrary unit; DOX, bare doxorubicin; PBS, phosphate-buffered saline.
