The cytocompatibility of HPZP@SST and HPZP-Ag@SST: (a) cell viability of hGFs treated with different concentrations of HPZP@SST for 24, 48, and 72 hr. n = 5; (b) cell viability of hOKs treated with different concentrations of HPZP@SST for 24, 48, and 72 hr. n = 5; (c) cell viability of hGFs treated with different concentrations of HPZP-Ag@SST for 24, 48, and 72 hr. n = 5; (d) cell viability of hOKs treated with different concentrations of HPZP-Ag@SST for 24, 48, and 72 hr. n = 5. Data are presented as the mean ± SD. , , , vs. control group.
