Abstract

Abstract: Herein, a collaborative precise antibacterial wound healing therapy nanoplatform integrating drug‐food homologous bioactive molecule (cinnamaldehyde, CA) with photothermal therapy (PTT) is presented. Copper‐gallic acids‐cinnamaldehyde‐polydopamine nanorods (Cu‐GA‐CA‐PDA NRs) with near‐infrared light (NIR)‐controlled CA release property are fabricated, which also integrate CA and photothermal synergistic sterilization, as well as antioxidant, anti‐inflammatory, and anti‐infection capacities. The characteristics of NIR‐mediated CA release and photothermal response of Cu‐GA‐CA‐PDA NRs support their excellent sterilization performance in vitro/in vivo. In addition, under the guidance of NIR, Cu‐GA‐CA‐PDA NRs can hinder the formation of inflammatory cells, reduce oxidative stress damage, accelerate the regeneration of skin tissues in S. aureus ‐infected wound sites, and achieve the goal of promoting wound healing. Therefore, NIR‐mediated Cu‐GA‐CA‐PDA NRs with multifunctional biological activities provide a highly competitive strategy for curing bacteria‐infected wounds. Abstract : A multifunctional "all in one" wound healing antibacterial therapy nanoplatform is designed based on drug‐food homologous bioactive molecule (cinnamaldehyde, CA) and photothermal collaborative precise therapy regulated by near‐infrared (NIR) light. This nanoplatform exhibits NIR‐mediated CA release, CA and photothermal synergetic sterilization, antioxidant, anti‐inflammatory, anti‐infection features, and excellent biocompatibility. Besides, this nanoplatform can effectively accelerate S. aureus ‐infected wound healing.
