Fig. 7. Confocal images of HeLa cells stained with calcein AM (green, live cells) and EthD-1 (red, dead cells). (A) Untreated cells; (B) treated with 8 nM AuNPs-dsDNA; (C) treated with 8 nM AuNPs@PDA-dsDNA; (D) 670 nm laser irradiation for 5 min; (E) treated with 8 nM AuNPs-dsDNA plus laser irradiation; and (F) treated with 8 nM AuNPs@PDA-dsDNA plus laser irradiation.
