Enhanced Antibacterial Activity of Highly Biocompatible Polymeric Core-Shell Levofloxacin Gold Nanocomposite Formulation Against Pseudomonas aeruginosa.

Using natural and synthetic polymers as the components for the core-shell nanocomposite preparation has received recent attention in biomedicine due to their high biocompatibility, high efficacy, and biodegradability. In this present investigation, chitosan-polyvinyl alcohol core-shell gold nanocomposite was synthesised adopting green science principles followed by fabrication with fluoroquinolone antibiotic levofloxacin (LE-CS-PVA-AuNC). Core-shell nanocomposite was prepared from biogenic gold nanoparticles, chitosan, polyvinyl alcohol polymer mixture, and levofloxacin under optimum conditions, and the synthesised nanocomposite exhibited a highly stable nanoarchitecture.
