Abstract
Biofilm infections present a formidable challenge in wound management due to their tolerance to antimicrobial treatments. This study introduces a novel hydrogel wound dressing designed to deplete pyruvate, a key metabolite in biofilm formation and maintenance, from the wound environment. Hydrogel sheets made from the natural polymer alginate crosslinked with calcium chloride (CaCl2) were synthesized with varied concentrations, with and without the pyruvate-depleting enzyme pyruvate dehydrogenase (PDH). Through analysis of mechanical properties, swelling behavior, morphology, porosity, and enzymatic activity, the study characterizes the hydrogels and demonstrates effective PDH entrapment within the sheets. Results indicate promising potential for biofilm management through pyruvate depletion. Future research will focus on optimizing PDH loading and assessing the dressing's efficacy in biofilm studies.
