Abstract

Abstract: Binary-blend films of furcellaran and gelatin (FUR/GEL) and FUR/GEL composite films reinforced with selenium nanoparticles (SeNPs) or silver nanoparticles (AgNPs) were prepared using a solution casting method. The effects of SeNPs and AgNPs on the physical, mechanical, structural, antibacterial properties of the furcellaran/gelatin-based films were examined. It follows from these examinations that the incorporation of SeNPs and AgNPs leads to an increase in thickness, water content, modulus of elasticity, elongation at break, and antimicrobial activity when higher parameters a*, b*, and ΔE are observed in nanocomposite films with AgNPs compared to those enriched with SeNPs. Compared with control film, the addition of nanoparticles significantly decreased solubility and swelling degree. Films containing SeNPs show greater antimicrobial activity against Escherichia coli, Staphylococcus aureus and multi resistant Staphylococcus aureus than films containing AgNPs.

Nanocomposite films were developed due to furcellaran-gelatin interactions. SeNPs incorporated films exhibited strong antimicrobial activity.
