Fig. 2From: A combined miR-34a and arsenic trioxide nanodrug delivery system for synergistic inhibition of HCC progression after microwave ablationCharacteristics of the As/miR34aNPs. A TEM images under different pH conditions. B Zeta potentials of As/miR34aNPs measured by DLS at different pH values. C Cell viability after treatment with blank nanoparticles was examined by MTT assay. D Drug release curves (pH 7.4 or pH 6.5, with or without GSH treatment). E miRNA agarose gel electrophoresis experiment. As/miR34aNPs were incubated with serum at different pH values for 24 h (pH 7.4 or pH 6.5, with or without GSH treatment)Back to article page
