Laser confocal fluorescence micrographs of HeLa cancer cells. HeLa cells incubated in the absence of Au/Ce NCs (A), in the presence of 50 μmol/L (B) and 150 μmol/L (C) Au/Ce NCs solutions for 24 h. (D) Relative fluorescence intensity variations along cross-sections a (in A), b (in B), or c (in C) (the color gradient coding illustrates the direction of the sampling). Fluorescence micrographs were collected by using a 488 nm fluorescence excitation wavelength.
