In vitro experiments of cellular uptake of MGNS/DOX in HeLa cell. (a) Fluorescence images of HeLa cell uptake of MGNS/DOX under different conditions at different time; (b) Normalized fluorescence intensity of the fluorescence images of Hela cells’ uptake of MGNS/DOX under different conditions at different time. The statistical analysis of all the data were performed by one-way analysis of variance (ANOVA) to get ±s.d., *P≤0.05 and n=3 for all the analysis.
