Abstract
In an effort to prepare a modern polysaccharide-based dressing for sustained/prolonged delivery of the antibacterial agent to prevent and control skin wound infection, ciprofloxacin (CP)-loaded sodium alginate (SA)-chitosan (CS) nanoparticles (NPs) were incorporated into novel arabinoxylan (AX)-pectin (PC) blended polymeric films by solvent casting. The CP-NPs were prepared by a two-step ionic interaction method with < 300 nm size, about 25 mV zeta potential, 74% CP-loading efficiency, and approximately round shape. The CP-NPs were incorporated in optimized AX-PC polymeric film prepared by using 2% AX and 2% PC with a plasticizer (2% glycerol) and then these films were characterized for suitability as a film dressing. The transparency, improved mechanical strength, thermal stability, water transmission, and exudate uptake characteristics indicated that CP-NPs incorporated AX-PC polymeric films were suitable for dressing applications. The CP-NPs incorporated AX-PC films exhibited sustained CP release (90% release in 36 h) and better antibacterial susceptibility as compared to free CP-containing AX-PC films. Thus, CP-NPs incorporated AX-PC films are promising dressing materials to prevent and control wound infection with prolonged antibiotic release.
