Viability of NIH-3T3 cells (a, b) and A549 cells (c, d) after ZnO-NP exposure determined with the CTB assay (a, c) or the MTT assay (b, d). The cells were encapsulated in hydrogel (a, c), seeded on scaffolds (b, d), or cultured on 2D monolayers. The signals of untreated cells were set as 100%. Data points are means ± SD for . .
