NIR-II Responsive Platinum-Engineered Vanadium Carbide MXene Endows Poly-L-Lactic Acid Bone Scaffold with Photothermal Antibacterial Property

Published on 2026-01-30 by Lin Sun, Zihao Zhang, Bingxin Sun, Zhiheng Yu, Guoyong Wang @MDPI

Abstract: Vanadium carbide (V2C) MXene shows great potential for addressing challenging implant-associated infections in bone regeneration due to its strong photothermal conversion efficiency. However, its photothermal efficacy is restricted to the near-infrared I (NIR-I) region due to a limited absorption range. To address this, we designed platinum nanoparticle-decorated V2C heterostructures (Pt@V2C) via an in situ growth method, leveraging Pt&amp;rsquo;s plasmonic and catalytic properties to extend[...]


Our summary: The study presents platinum-decorated vanadium carbide MXene heterostructures that extend photothermal efficacy to the NIR-II region. These structures are integrated into poly-L-lactic acid scaffolds, achieving high photothermal conversion efficiency and significant antibacterial effects.
