Fig. 3From: HB5 aptamer-tagged graphene oxide for co-delivery of doxorubicin and silibinin, and highly effective combination therapy in breast cancerAFM images (A, B), zeta potential values (C), FTIR spectroscopy measurements (D), and UV–Vis spectral absorbance (E) of cGO and cGO-aptamer. F Agarose gel electrophoresis confirmed the successful HB5 absorption on the cGO surface.
