In this study, we fabricated a novel composite nanofibrous dressing composed of chitosan (CS), ulvan (UL), and polyvinyl alcohol (PVA) using the electrospinning technique. The use of water\u2010soluble polymers ensured biodegradability, while citric acid (CA), a green cross\u2010linker, enhanced mechanical stability. SEM analysis revealed uniform, smooth nanofibers with diameters ranging from 100 to 350\u2009nm. Characterization using ATR\u2010FTIR, TGA, and XRD confirmed the absence of undesirable polymer interactions and verified the structural integrity of the dressing. In\u00a0vitro evaluations showed excellent mechanical strength upto 5.51\u2009\u00b1\u20090.012\u2009MPa, water retention (1059.05\u2009\u00b1\u200910.5\u2009g\/m\n                    <jats:sup>2<\/jats:sup>\n                    \/24\u2009h), high porosity (92.49%\u2009\u00b1\u20094.6%), and a controlled degradation rate, supporting gas exchange, nutrient diffusion, and tissue regeneration. Cell culture studies demonstrated steady cell proliferation, and the dressing also exhibited promising blood\u2010clotting ability in TAT analysis. In\u00a0vivo wound contraction and histological studies in the Sprague\u2013Dawley rat model confirmed complete healing (with a wound closure rate of 93.29%\u2009\u00b1\u20092.29%) with new skin formation. Overall, the UL\/CS\/PVA composite nanofibrous dressing offers an effective and sustainable approach for accelerated wound healing while overcoming the limitations of conventional dressings.\n
