| Abstract Scope |
Antibacterial materials are needed in biomedical and food packaging industry, however, the use of toxic reagents is of concern to the scientific community. Taking advantage of the increase in cocoa cultivation worldwide, which generates a large amount of waste, this study aimed to develop a bionanocomposite from cocoa waste with antibacterial properties. Bionanocomposite films were made from a cocoa waste matrix containing zinc oxide nanoparticles synthesized by green chemistry using cocoa leaf extract as a reducing agent. The physicochemical and functional properties of the films were characterized and their antibacterial activity against E. coli was tested. The swelling rate of the films increased at basic pH, which is desirable for the absorption of exudate from chronic wounds. Marked antibacterial activity against E. coli was observed. Overall, these findings suggest that this novel bionanomaterial may be a promising and sustainable alternative in the design of biomedical solutions and food packaging. |
