Characterization of CMCNPs. (A-E) TEM images of PAM-SiO₂, Gl261-PAM-SiO₂, B16-PAM-SiO₂, 4T1-PAM-SiO₂, and RAW-PAM-SiO₂, with a scale bar of 200 nm. (F) Particle sizes of the five nanoparticles under an electron microscope: the PAM-SiO₂ diameter was 75.23±7.47 nm (n=10, the same as below); the Gl261-PAM-SiO₂ diameter was 98.45±7.37 nm; the B16-PAM-SiO₂ diameter was 90.31±5.53 nm; the 4T1-PAM-SiO₂ diameter was 96.02±5.91 nm; and the RAW-PAM-SiO₂ diameter was 92.35±6.94 nm. (G) Zeta potential of PAM-SiO₂, Gl261-PAM-SiO₂, B16-PAM-SiO₂, 4T1-PAM-SiO₂, and RAW-PAM-SiO₂ (n=6). (H) The encapsulation efficiency of the CMCNPs in each group. (I) In vitro release profiles of CMCNPs and NPs in PBS (n=3).
