Figure 5.

Antimicrobial CP-containing cryogels are cytocompatible towards murine fibroblasts. Confocal images showing mouse embryonic fibroblast NIH/3T3 cells cultured for 24 h in three CP-containing HAGM cryogels: (a) 0%, (b) 0.1%, and (c) 0.2% CaO₂. Red color depicts dead cells, blue color represents cell nuclei, green color highlights cell cytoskeleton and yellow color shows the polymer network of cryogels. (d) Evaluation of NIH/3T3 cell viability (%). Scale bars = 200 µm (large confocal images) and 100 µm (inset confocal images). Data are presented as the mean ± standard error of the mean (n = 4).
