Summary

Infection remains one of the hardest obstacles in non-healing wounds, and antibiotic resistance has made straightforward drug loading less effective. This study compares two ways of delivering norfloxacin from polysaccharide scaffolds - as free drug, or bound to montmorillonite as a nanocomposite - across three scaffold types based on chitosan, chitosan/chondroitin sulfate and chitosan/hyaluronic acid. Putting the two delivery strategies side by side in identical scaffolds isolates the contribution of the clay carrier to release behaviour and antibacterial effect.
