Laser confocal fluorescence micrographs of HepG2 cells and L02 cells. (A) HepG2 cells without Au/Ce NCs treatment. (B) HepG2 cells treated with 150 μmol/L Au/Ce NCs solutions for 24 h. (C) L02 cells without Au/Ce NCs treatment. (D) L02 cells treated with 150 μmol/L Au/Ce NCs solutions for 24 h. The micrographs of HepG2 cells were acquired by 20× IR coated objective. The micrographs of L02 cells were collected by 63× IR coated objective. The excitation wavelength was 488 nm.
