From: In situ valence-transited arsenic nanosheets for multi-modal therapy of colorectal cancer
a, b TEM and AFM images of CAA-PEG NSs. c The zeta potential of CAA and CAA-PEG NSs (Data are presented as mean values +/− SD, n = 3 independent experiments). d Loading efficiency of As, Cu, AOAA in CAA-PEG NSs (Data are presented as mean values +/− SD, n = 3 independent experiments). e Elemental mapping of CAA-PEG NSs. f Molecular dynamics simulation of CAA NSs formation process. The hydrogen bonds formed during the CAA NSs formation, AOAA and H2O (g), arsenate ions and H2O (h), and arsenate ions and AOAA (i), respectively. The dispersion stability (j) and particle size change (k) of CAA NSs and CAA-PEG NSs in PBS (Data are presented as mean values +/− SD, n = 3 independent experiments. Two-way ANOVA analysis and SÃdÃk’s Multiple Comparison Test was used to compare the two groups at the same time point. P values were presented in absolute value in the figures).
