Summary: In this study, thymol-containing wound dressing films were prepared using polysaccharide polymers. The films exhibited suitable swelling ratios, hydrolytic degradation, and water vapor transmission rates for wound healing applications. The addition of thymol increased the elongation at break value of the films and influenced the release amount of thymol. Furthermore, the films showed good biocompatibility and enhanced migration and proliferation of fibroblast cells.

Summary: The dynamic adsorption and desorption behaviors of rosin colloids onto and from CNFs and TOCNFs in aqueous media were investigated using QCM-D measurements. The effects of maleic anhydride modification, anionic surfactant, and Alum addition on the adsorption were studied. The results showed that maleic anhydride modification contributed to particle size reduction, an increase in Tg, and enhanced stability, while using an anionic surfactant increased the particle size and ionicity. The adsorption of rosin colloids was affected by the surface charge of CNFs and the presence of Alum.

Summary: Biodegradable materials based on PLA and a phenolic free modified rosin resin were studied under composting conditions. The resin was blended with different concentrations using industrial plastic processing techniques. The effects of the resin on PLA's compatibility, physical performance, water absorption, mechanical behavior, thermal stability, and microstructure were assessed. The incorporation of the resin decreased thermal degradation resistance and slowed down composting disintegration. Higher resin content resulted in delayed water diffusion and decreased diffusion coefficients. Mechanical properties decreased, but a saturation effect was observed at resin contents higher than 3 phr. The optimal amount for good interaction, complete miscibility, and material cohesion was found to be 3 phr.

Summary: A novel and portable cotton swab-based fluorometry was developed for the detection of 3-aminosalicylic acid (3-ASA) and 5-aminosalicylic acid (5-ASA). This method utilized silver (Ag)-doped black phosphorus quantum dots (Ag@BPQD) to enhance fluorescence. The linear range, detection limit, and recovery range for 3-ASA were 0-90 μM, 0.10 μM, and 98.0-104.3% respectively, while for 5-ASA they were 0-120 μM, 0.12 μM, and 98.0-101.3% respectively. By mixing different ratios of 3-ASA and 5-ASA, the fluorescence exhibited different colors. The proposed portable sensing method using Ag@BPQD and cotton swabs allows for convenient and efficient detection of 3-ASA and 5-ASA in environmental and biological samples, with high accuracy and portability requirements.

Summary: In this study, bacterial cellulose from nata de coco was modified into carboxymethyl cellulose (CMC) form using various concentrations of monochloroacetic acid (MCA), with the optimum treatment found to be 24 g of MCA per 15 g of cellulose. Different concentrations of MCA affected the degree of substitution (DS), chemical structure, viscosity, color, crystallinity, and morphology of CMCn. The use of various MCA concentrations also increased the mechanical properties and water vapor permeability of CMCn, which were related to the DS value.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
