Uptake pathway of layered double hydroxides (LDHs) into cells. (a) A representative process of clathrin-mediated endocytosis (b) Confocal microscopy, which includes the colocalization of fluorescein 5′-isothiocyanate (FITC)-LDH and clathrin in MNNG/HOS cells (involving the localization of (1) the nucleus, (2) clathrin, and (3) FITC-LDH in MNNG/HOS cells, as shown in (4) the merged image). Cells were incubated with FITC-LDH for 2 h, treated with clathrin antibodies, and stained by Texas Red and 4′,6-diamidino-2-phenylindole. Scale bar = 10 µm. (Reprinted with permission from Ref.
