Antibacterial activity of CP-containing microcomposite cryogels. (a) Residual CFU i.e., colony forming units per ml of MRSA after 6 h of contact period within different cryogels; namely CP-free cryogels (0% CaO₂), CP-containing (0.1% CaO₂) cryogels, and CP-containing (0.2% CaO₂) cryogels. (b) Cross-sectional SEM of CP-free cryogels (0% CaO₂), and (c) CP-containing (0.1% CaO₂) cryogels. (d) Residual CFU/ml P. aeruginosa after 6 h of contact period across different cryogels. (e) cross-sectional SEM of CP-free cryogel (0% CaO₂), and (f) CP-containing (0.2% CaO₂) cryogels. Data are representative of three independent experiments and are presented as the mean ± standard error of the mean (n = 4). For visualization, MRSA and P. aeruginosa were pseudocolored in yellow and green, respectively. Scale bars = 10 µm.
