Abstract

Aim: To develop a biocompatible conjugated ciprofloxacin-PEG-FeO nanodelivery system with increased efficacy of available therapeutics in a controlled manner. Materials & methods: FeO nanoparticles were synthesized by chemical and biological methods and modified as ciprofloxacin-PEG-FeO nanoformulations. After initial antibacterial and cytotoxicity studies, the effective and biocompatible nanoformulations was further fabricated as nanotherapeutics for in vivo studies in mouse models. Results: Chemically synthesized ciprofloxacin-PEG-FeO nanoformulations demonstrated boosted antibacterial activity against clinically isolated bacterial strains. Nanoformulations were also found to be compatible with baby hamster kidney 21 cells and red blood cells. In in vivo studies, nanotherapeutic showed wound-healing effects with eradication of Staphylococcus aureus infection. Conclusion: The investigations indicate that the developed nanotherapeutic can eradicate localized infections and enhance wound healing with controlled cytotoxicity.

Keywords: CIP-PEG-FeO nanoformulation; antibacterial; controlled cytotoxicity; mouse model; therapeutic agents.
