Bioinspired Heteromultivalent Chitosan-α-Fe₂O₃/Gadofullerene Hybrid Composite for Enhanced Antibiotic-Resistant Bacterial Pneumonia
Herein, we have designed and developed a heteromultivalent chitosan base α-Fe₂O₃/Gadofullerene (GdF) hybrid composite through a simple chemical precipitation method. Unlike other methods, the addition of external stabilizing agents to generate GdF nanoparticles (NPs) was not necessary herein. The prepared chitosan-α-Fe₂O₃/GdF hybrid nanocomposites were characterized using UV, FT-IR, XRD and morphological microscopic analyses. The results showed that α-Fe₂O₃ and GdF hybrid nanocomposites were successfully grown on the surface of chitosan. The FT-IR vibration peaks showed the formation of Fe₂O₃ NPs, and the vibration peak for Fe-O was 568 cm-1. The broad absorption peak observed in the range of 250-350 nm and a sharp absorption peak at 219 nm represents the UV absorption of the synthesized hybrid composites. XRD pattern showed sharp peaks of crystallinity and purity of α-Fe₂O₃ nanoparticles. Finally, the synthesized chitosan-α-Fe₂O₃/GdF hybrid composites were screened for their antibacterial resistance against the Escherichia coli, Pseudomonas aeruginosa, Bacilus subtilis, and Staphylococcus aereus. In addition, in vitro biocompatibility results exhibited that developed hybrid samples have provided high cell compatibility with fibroblast (L929) cell line. The in vivo bio inspired nanotherapeutics have the potential action to effective inhibition ability on antibiotic-resistant P. aeruginosa, which has been main factor of inducing pneumonia. In conclusion, we expect biomimicking systems combined with the effective antibacterial agent could be the suitable next generation therapeutic potential factors for prevention and treatment of antibiotic-resistant pneumonia.
