Periodontitis, a prevalent chronic inflammatory disease worldwide, is triggered by periodontopathogenic bacteria, resulting in the progressive destruction of periodontal tissue, particularly alveolar bone. To effectively address periodontitis, this study proposed nanoformulation known as CuS@MSN-SCS. This formulation involves coating citrate-grafted copper sulfide (CuS) nanoparticles with mesoporous silica (MSNs), followed surface modification using amino groups and sulfated chitosan (SCS) through electrostatic interactions. The objective to achieve efficient bacteria removal inducing ROS signaling pathways mediated Cu2+ ions. Additionally, it aims promote bone regeneration Cu2+-induced pro-angiogenesis SCS-mediated regeneration. As anticipated, regulating charges, negatively charged CuS capped sodium citrate were successfully coated MSNs, subsequent introduction amine (3-aminopropyl)triethoxysilane was incorporation SCS interactions, formation developed verified not only significantly exacerbate oxidative stress Fusobacterium nucleatum, thereby suppressing growth biofilm vitro, but also alleviate response without evident biotoxicity an vivo rat periodontitis model. These findings contribute therapeutic effect on periodontitis. Overall, for combating facilitating regeneration, demonstrating promising potential clinical treatment
