Recently, nucleic acid-modified nanomaterials have attracted significant attention for their potential in regulating inflammation. Among these, most nanomaterials, such as spherical nucleic acids, tend to exhibit pro-inflammatory effects. In this study, we identified for the first time that poly-T sequence-modified gold nanorods (PTM AuNRs) possess significant anti-inflammatory properties. The PTM AuNRs demonstrated excellent biocompatibility and efficacy in treating ligation-induced periodontitis. PTM AuNRs modulate immune responses by inhibiting the differentiation of pro-inflammatory M1 macrophages and reducing pro-inflammatory cytokine levels through promoting AMPK activation. When administered via local injection, PTM AuNRs effectively suppress inflammatory response and inflammatory cell infiltration, downregulate inflammatory cytokine levels, and mitigate collagen fiber degradation and alveolar bone loss. Together, these findings highlight PTM AuNRs as a promising and innovative therapeutic strategy for periodontitis management.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"89 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we present the development of crystallinity-controlled heterostructures based on nickel and cobalt oxides (NiCo<sub>2</sub>O<sub>4</sub>/NiO and NiO/Co<sub>3</sub>O<sub>4</sub>) with different morphologies (urchin- and flower-like structures, e.g., U-NiCo<sub>2</sub>O<sub>4</sub>/NiO and F-NiCo<sub>2</sub>O<sub>4</sub>/NiO) to investigate the influence of heterostructure combinations and morphologies on electrochemical performance in LIBs. The morphologies of the heterostructures were controlled by adjusting the fluoride concentration during the synthesis of the nickel–cobalt (Ni–Co) precursor, while heterostructure combinations were regulated by heat treatment under specific conditions. When used as anodes for LIBs, electrochemical analyses revealed that the carbon-coated urchin-like U-NiCo<sub>2</sub>O<sub>4</sub>/NiO (U-NiCo<sub>2</sub>O<sub>4</sub>/NiO@C) sample provided more efficient charge transfer and a shorter Li-ion transport pathway compared to its counterpart (F-NiCo<sub>2</sub>O<sub>4</sub>/NiO@C) due to its high surface area and distinctive morphological features. In addition, U-NiCo<sub>2</sub>O<sub>4</sub>/NiO@C exhibited superior electrochemical performance as an anode in LIBs than U-NiO/Co<sub>3</sub>O<sub>4</sub>@C, indicating that the advantageous effects of BTMO over UTMO can effectively enhance LIB performance.
