a Relative viability of HCT-116, HeLa, A549, and MCF7 cells after exposure in B@PDA-based medium (25–500 ppm) for 48 h. b Relative viability of HCT-116 cell incubated with B@PDA (1.5, 3, 6, 12, 24, 48, and 96 ppm) for 4 h and after photothermal treatment (1 W cm−2, 808 nm, 10 min,). c–e were treated with the same condition as (b) for HeLa, MCF7, and A549, respectively. f Corresponding laser scanning confocal microscopy (scale bars, 50 µm for all panels) of HCT-116 cells stained with PI (dead cells, red) and calcein AM (live cells, green)
