Abstract
Periodontitis is an inflammatory disease caused by bacterial infection. Excessive immune response and high levels of reactive oxygen species (ROS) further lead to the irreversible destruction of surrounding tissues. Developing new antimicrobial materials that regulate the immune system to resist inflammation can effectively treat periodontal inflammation. A nanoplatform integrating Ag+, photothermal therapy (PTT), and procyanidins (PC) for precision antibacterial and synergistic immunotherapy for periodontitis was proposed. This work loaded PC into AuAg nanoparticles, and the resulting nanocomposite was named AuAg-PC. PTT can effectively remove pathogenic bacteria, but high temperatures can cause tissue damage. Ag+ contributes to the preparation of a nanoparticle branched structure that improves the photothermal efficiency and helps PTT achieve an excellent antibacterial effect and avoid periodontal tissue damage. PC regulates host immunity by eliminating intracellular ROS, inhibiting inflammatory factors, and regulating macrophage polarisation in periodontal disease sites. It enhances the host's resistance to bacterial inflammation. AuAg-PC exerted an excellent anti-inflammatory effect and promoted tissue repair in animal periodontal inflammation models. Hence, AuAg-PC significantly combats periodontal pathogens and shows great application potential in the photothermal-assisted immunotherapy of periodontitis. This design provided a new controllable and efficient treatment platform for controlling persistent inflammation infection and regulating immunity.

[PMID: 36188310 PMCID: PMC9520686 DOI: 10.1021/acsomega.2c02718] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 08/25/2022] [Indexed: 06/16/2023]
Abstract
Silver (Ag) has been demonstrated to have excellent performance to kill bacteria, fungi, and some viruses because it can release positively charged Ag ions with highly antibacterial and antifungal activities. However, effectively controlling the slow release of Ag ions is the key to preparing high-performance Ag-based antibacterial agents, which remains a challenge. In this work, we have developed a new Ag-based antibacterial agent composed of Ag ions loaded on 2D anionic 2D Sb3P2O14 3- nanosheets (denoted as Ag-Sb3P2O14). 2D anionic nanosheets not only adsorb a large amount of Ag ions but also control their slow release through electrostatic interaction between nanosheets and Ag ions. 2D Ag-Sb3P2O14 nanofillers enable excellent high antibacterial activities for the poly(vinylidene fluoride) (PVDF) film composites against microorganisms including Escherichia coli and Staphylococcus aureus. Moreover, the PVDF membrane with 5 wt % 2D Ag-Sb3P2O14 nanofillers can kill almost all bacterial after 50 times washing, demonstrating its excellent durable antibacterial activities. This work opens up a new and promising route to durable Ag-based antibacterial agents for polymer-based composites.

Abstract
Traditional antimicrobial methods, such as antibiotics and disinfectants, may cause adverse effects, such as bacterial resistance and allergic reactions. Photocatalysts based on titanium dioxide (TiO2) have shown great potential in the field of antimicrobials because of their high efficiency, lack of pollution, and lack of side effects. This paper focuses on the antimicrobial activity of TiO2 under different light sources. To improve the photocatalytic efficiency of TiO2, we can reduce electron-hole recombination and extend the photocatalytic activity to the visible light region by doping with different ions or compounds and compounding with polymers. We can also improve the surface properties of materials, increase the contact area with microorganisms, and further enhance the resistance to microorganisms. In addition, we also reviewed their main synthesis methods, related mechanisms, and main application fields to provide new ideas for the enhancement of photocatalytic microorganism performance and application popularization in the future.
