A novel platform for targeted on-demand prodrug ascorbic acid (AA) delivery is fabricated using a bacterial hyaluronidase sensitive graphene-mesoporous silica nanosheet@hyaluronic acid-magnetic nanoparticles as the nanocarrier to treat bacterial infections. The released AA can be converted to detrimental •OH in situ on the surface of bacteria. With the chemo-photothermal synergistic effect, the designed antibacterial system can effectively inactivate bacteria and disperse stubborn biofilm.
一种新型的靶向按需前体药物抗坏血酸（AA）递送平台是使用细菌透明质酸酶敏感的石墨烯-介孔硅纳米片@透明质酸-磁性纳米颗粒作为纳米载体来治疗细菌感染而构建的。释放的 AA 可以在细菌表面原位转化为有害的 •OH。通过化学-光热协同作用，设计的抗菌系统可以有效地灭活细菌并分散顽固的生物膜。
