Elevated temperatures can deactivate tissues in the burn wound area, allowing pathogenic bacteria to multiply on the wound surface, ultimately leading to local or systemic infection. An ideal burn dressing should provide antibacterial properties and facilitate painless dressing changes. We utilized silk microfibers coated with 2, 3, 4‐trihydroxybenzaldehyde (referred to as mSF@PTHB) to in situ reduce AgNO3 to silver nanoparticles (AgNPs) in a hydrazide hyaluronic acid based hydrogel. The findings indicated a more homogeneous distribution of the silver elements compared to directly doped AgNPs, which also conferred antioxidant and antibacterial properties to the hydrogel. Moreover, hydrogels containing pH‐responsive dynamic acylhydrazone bonds can undergo a gel‐sol transition in a weak acid environment, leading to the painless removal of adhesive hydrogel dressings. Notably, the on‐demand replaceable self‐healing antioxidant hydrogel dressing exhibited antibacterial effects and cytocompatibility in vitro, and the wound healing performance of the hydrogel was validated by treating a burn mouse model with full‐thickness skin defects. It has been demonstrated that hydrogel dressings offer a viable therapeutic approach to prevent infection and facilitate the healing of burn wounds.This article is protected by copyright.

“…[16] In recent years, various plasmonic nanomaterials have garnered wide acceptance in the development of photothermal surfaces. [3,17,18] Although both AuNPs and AgNPs, owing to their strong plasmonic nature, have dominated the field of photothermal applications, particularly in the biomedical sector for photothermal therapeutics, [19][20][21][22][23][24] existing literatures show a bias toward the use of AuNPs in the development of transparent photothermal surfaces. However, a recent study comparing AuNPs and AgNPs for photothermal heating demonstrated that AgNPs below 20 nm in size can achieve higher temperature elevation than AuNPs.…”

Transparent photothermal coatings based on plasmonic noble metals often face a trade‐off between achieved temperatures and transmittances. This challenge arises from the fact that plasmonic nanoparticles (NPs), which rely on their size and structures, selectively absorb light of various wavelengths and convert it into heat. In the cases of randomly arranged plasmonic NPs, absorbances are predominantly in the visible range, leading to lowered transmittances. In this work, the self‐assembly behavior of a biotemplate containing flexible potato virus A (PVA) is used to produce network‐like surface patterns with controllable intermittent vacancies. These templates effectively anchor silver nanoparticles (AgNPs), forming dense arrays of plasmonic hotspots interspersed with vacant regions. With this approach, a temperature increase of 21 °C above ambient temperature under 1‐sun radiation is achieved while maintaining a visible light transmittance as high as 78% measured at 550 nm wavelength. The PVA biotemplated AgNPs show excellent potential as antifogging coating, exhibiting 2–3 times faster defogging rates compared to uncoated samples in both indoor and outdoor conditions. Overall, a platform is presented for biotemplating metal NPs, the development of long‐range surface patterns with controlled vacancies, and the demonstration of transparent photothermal activity with an antifogging application.
