Cellulose and chitin nanocoating with antibacterial properties = Cellulose and chitin nanocoating with antibacterial properties

초록

To address the limitations of traditional food packaging, such as mechanical, microbial, and chemical vulnerabilities, alongside environmental concerns related to metallic or halogenated polymeric coatings, we developed a novel coating for poly(ethylene terephthalate) (PET) films. This coating encompasses four key attributes: sustainability, self-cleaning capabilities, transparency, and effective barriers against oxygen and moisture.Moreover, the antibacterial efficacy of our bioorganic nanoparticles was assessed against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. Our findings revealed that the growth of both bacterial strains was significantly reduced upon exposure to our enhanced nanoparticle formulation Keywords: cellulose nanomaterials, chitin nanomaterials, gas barrier, self-cleaning, bionanomaterials
