Physical and chemical properties of anti-senescence ion-delivering nanocarriers (AINs). A A transmission electron microscopy (TEM) image of AINs (high power magnification at the top-left corner). B Size distribution of AINs, as measured using TEM. C Energy-dispersive X-ray spectroscopy (EDXS) analysis of AINs. Iron atom peaks are indicated with white arrows. D X-ray diffraction (XRD) patterns of AINs. Iron ion patterns are emphasized using blue squares. E Ultraviolet-visible spectroscopy (UV-Vis) spectra of AINs at pH 7.0 (blue line), gold nanoparticles (Au) at pH 7.0 (red line), and AINs at pH 4.5 (black line). Peak shifts owing to the present of iron. F The component gold/iron ratio profile of AINs as estimated using EDXS under the different pH conditions at 12 h (n = 3, *p < 0.05 versus standard group)
