a Cellular uptake of DOX, the DOX@TDN, and the DOX@Apt-TDN. Modified with the aptamer Gint4.T, the Apt-TDN could deliver more doxorubicin to U87MG cells than the TDN. In addition, the TDN could carry more drug to cells than the drug alone. The scale bars indicate 50 μm. b Semi-quantitative analysis of the fluorescence intensity of doxorubicin with PBS, DOX, DOX@TDN, and DOX@Apt-TDN treatment (compared to blank: *p < 0.05, **p < 0.01)
