Abstract
Staphylococcus aureus (S. aureus) is an opportunistic bacterium that causes several infections in humans. However, chronic biofilms remain a major challenge associated with recalcitrance toward traditional treatments. Herein, an antibacterial hydrogel composed of antisense DNA oligonucleotides, graphene oxide and alginate is construed for biofilm management and infection care. The hydrogel is established through noncovalent binding and possesses injectability and degradability properties. Furthermore, hydrogels present controllable release of cargoes, genetic targeting antibacterial effects and stem cell supporting capabilities. Our in vivo results reveal a high antibiofilm performance and good biocompatibility, which significantly improve tissue regeneration. The hydrogel inhibits biofilm formation by decreasing the expression of YycFG with antisense and viability of strains by graphene oxide. Thus, antisense hydrogels can be a promising antibacterial bioactive material for potential therapeutic S. aureus infection.
