Bioinspired nonantibiotics can prove to be a better and an efficient tool to fight against antimicrobial resistance. In our study, biomaterial composed of zinc-carboxymethyl chitosan (CMC)-genipin was investigated for this purpose. Briefly, CMC was synthesized and transformed to porous scaffolds using the freeze drying method. The scaffolds were cross-linked and stabilized with genipin and zinc (2 M zinc acetate), respectively. FTIR spectroscopic data testified Zn complex formation and pointed out the absence of water molecule like that of zinc motif containing proteins. Hence, the complex may be termed as biomimetic. Genipin (0.5%) cross-linking appeared to contribute additively to the wet compressive strength of the zinc-CMC scaffolds. Biodegradation data revealed better stability of CMC-genipin-zinc scaffolds in enzymatic and nonenzymatic conditions than their redundant controls. The scaffolds seem to support adhesion and proliferation of human dental pulp stem cells and were hemocompatible to human red blood corpuscles, as revealed by scanning electron microscopy. The scaffolds were found to be antibacterial and mildly antibiofilm when tested against biofilm-forming bacteria, that is, Staphylococcus aureus (ATCC 9144), making it a potential nonantibiotic-like biomaterial. To conclude, this organometallic complex-based biomaterial may potentially serve as a weapon against antimicrobial resistance. Furthermore, the biomaterial potentially finds its application in dental, maxillofacial, and orthopedic tissue engineering applications.
