Porous hydrogel of siloxane-modified polyvinyl alcohol/polydopamine containing berberine chloride, exhibiting robust antibacterial activity and promoting the healing of MRSA-infected wounds

Advanced and novel effective wound dressings that decrease wound infections are essential for clinical application. In this study, a multifunctional hydrogel was engineered based on polyvinyl alcohol (PVA), polydopamine (PDA), and porous silica (PSi), loaded with berberine chloride (Bbn), for the treatment of MRSA-infected wounds. The PVA@PSi/PDA-Bbn hydrogel was fabricated via sol-gel and self-polymerization methods, forming a porous, adhesive, and photothermal-responsive matrix. The hydrogel...
