Fluorescence microscopic images of HUH-7 cells treated with N-CQDs, Co2+ and DCA (A) cell treated with N-CQDs at concentration 10 µg/ml (B) phase contrast images of (A). (C) Cell treated with N-CQDs + Co2+ at concentration 10 µg +10 µg/ml (D) phase contrast images of (C). (E) Cell treated with N-CQDs + Co2+ + DCA at concentration 10 µg+10 µg+20 µM. (F) phase contrast images of (E). All images are acquired with 20x objective lens with applied wavelength λex = 340 nm, λem = 459 nm filter used DAPI.
