AB  - Environmentally benign pH-indicating wound dressing comprised of carbohydrates chitosan (CH) and pectin (P), and anthocyanin grape (AG) dye is created via layer-by-layer assembly. Cotton fabric coated with eight bilayers of (CH-AG)4/(P-AG)4 deposited 1.97 % AG-dye. It exhibited a visible and immediate color change from pink to violet-blue while increasing its pH value from 6 to pH 7, matching the turning pH point of healing into an infected wound. Color transition of AG-dye in water-based buffers, tested by VIS-spectroscopy, shows the same color change when the pH value increased from 6 to 7. This coating imparts excellent antimicrobial activity against Gram-positive bacteria Staphylococcus aureus and yeast Candida albicans, moderate antibacterial activity against Gram-negative Escherichia coli bacteria, and no cytotoxicity on human fibroblast cells (MRC-5). This research proposes a sustainable, low-cost, and simple method for obtaining smart wound dressing that provides real-time monitoring of the wound pH.

AB  - The flammability of polyester textiles remains a significant challenge that must be overcome to allow their use in a variety of clothing and upholstery applications. In this work, water-based polyelectrolyte solutions composed of chitosan (CH) and pectin (P), as carbon-rich biomacromolecules, and mono ammonium phosphate (MAP) were deposited on enzyme/corona modified polyester via layer-by-layer (LbL) deposition. Four bilayers (BL) of 1% CH3/(1% P-30% MAP)4.2 renders the polyester fabric self-extinguishing in vertical flame testing. This recipe yields a 42.6% lower peak heat release rate and a nearly 40% reduction in the fire growth capacity, compared to uncoated polyester, as measured by micro cone calorimetry. The enzyme/corona modification, combined with the CH/(P-MAP) intumescent system, results in a very effective flame retardant treatment with few BL deposited.
