Experimental results of acellular swim bladder-loaded AgNPs: Optical photographs of swim bladder before and after decellularization and impregnation with AgNPs (A), where a1, a2, and a3 represent fresh swim bladder, decellularized, and AgNP-soaked samples, respectively; histological staining analysis of fresh swim bladder before (b1, b4, and b7) and after decellularization with 0.5% SDS (b2, b5, and b8) and 1.0% SDS (b3, b6, and b9) (B), among which b1–b3, b4–b6, and b7–b9 are H&E, picro-fuchsin, and orcein-picroindigocarmine staining, respectively; bacterial experiment results (C), in which BS, EC, PA, ST and SA represent Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium and Staphylococcus aureus, respectively.
