Functional finishing of medical fabrics using CeO2/allicin nanocomposite for wound dressings

Abstract With the potential to scavenge reactive oxidant species, cerium oxide nanoparticles are found to be important in biomedical industry as antioxidant material. In this study, CeO 2 /allicin nanocomposite impregnated woven and non-woven fabrics are studied for the wound healing application by analysing their antimicrobial efficacy against Escherichia coli and Staphylococcus aureus . The diallyl thiosulfinate allicin compound extracted from Allium sativum impartsmicrobicidal property to the antioxidant CeO 2 nanoparticles. Shift in the absorption peak in the UV–Visible spectrum between CeO 2 and allicin incorporated CeO 2 confirms the nanocomposite formation. Raman spectrum shows characteristic peaks of the CeO 2 nanoparticles. The synthesized nanoparticles are in the size range of 5–10 nm as confirmed from Raman and TEM. XRD and FTIR confirm the nanocomposite incorporation into the fabrics. In addition, leaching study was performed to ensure the durability of the fabrics.
