Characteristics of CHC and DMC-CHC NPs. (A) TEM morphology of CHC and DMC-CHC NPs (scale bar: 200 nm). Left one is unloaded CHC, and right one is DMC-CHC nanoparticles. (B) Left panel: effect of DMC on the viability of A549 cells. Right panel: effect of free DMC-CHC NPs on the viability of A549 cells. (C) CHC nanomatrix (6.25, 12.5, 25, 50, and 100 μg/mL) were incubated with A549 for 24 h, 48 h, and 72 h. The results showed that the CHC nanomatrixes demonstrated no cytotoxicity on A549. Each data point is represented as the mean ± SD (n = 3). Error bars represent standard deviation. * Indicates the values significantly different from the control time points, 24 h, 48 h, and 72 h., respectively. (* p < 0.05; ** p < 0.01).
