Fig. 6From: Devising Hyperthermia Dose of NIR-Irradiated Cs0.33WO3 Nanoparticles for HepG2 Hepatic Cancer CellsOptical confocal images. The a, d fluorescence, b, e BF and c, f composite optical images of the HepG2 cells incubated with and without the fNPs, as the corresponding experimental and control groups, are presented in the a–c top and d–f bottom rows alongside g a histogram of the average fluorescence intensities. Scale bars represent 20 μm; the laser excitation wavelength is 488 nmBack to article page
