Fig. 5From: Redox-responsive tumor targeted dual-drug loaded biocompatible metal–organic frameworks nanoparticles for enhancing anticancer effectsa The flow cytometry analysis of cellular uptake of the control group, DCA-UiO-DTDP and DCA-UiO-DTDP-FA at 16 h for MDA-MB-231, and b corresponding mean fluorescent intensities with DCA-UiO-DTDP and DCA-UiO-DTDP-FA nanoparticles. The difference of tumor uptake in DCA-UiO-DTDP and DCA-UiO-DTDP-FA groups were statistically significant (**P < 0.01)Back to article page
