Abstract:
Wound healing is a complex multistep process. Wound healing materials should have good antibacterial activity against wound infection causing microbes. Curcumin has effective antimicrobial activity, anti-inflammatory and antioxidant property. Titanium dioxide (TiO2) is a biocompatible, nontoxic material used for many biomedical applications. The Usage of curcumin tagged TiO2 nanoparticles for wound healing activity is promising due to the properties of both curcumin and TiO2. We have synthesized curcumin tagged TiO2 nanoparticles. The synthesized materials are characterized with XRD, FTIR and TEM. TiO2-Cur nanocomposite was incorporated into poly vinyl alcohol (PVA) and sodium alginate (SA) patch. The PVA/SA/TiO2-Cur patch was prepared by gel casting method. Antibacterial efficiency of PVA/SA/TiO2-Cur patch was analyzed. Further, in vivo studies conducted on Wister rats confirmed the enhanced wound healing property of the PVA/SA/TiO2-Cur patch. Our results suggest that this could be an ideal biomaterial for wound dressing applications.
