Sprayable hydrogels have attracted considerable attention due to their favorable fitting with irregular wounds. However, the development of hydrogels with programmable anti-bacterial, anti-inflammatory, and regenerative properties to match the healing process still faces severe challenges. Herein, a versatile strategy is demonstrated to develop sprayable and photothermal fiber-embedded hydrogel dressings by incorporating the gold nanorods (AuNRs) and anti-inflammatory drug diclofenac sodium (DS)-loaded poly(lactic-co-glycolic acid) (PLGA) electrospun fibers into the stromal-cell-derived factor 1α (SDF-1α)-immobilized gelatin methacrylate hydrogel. Benefiting from the photothermal conversion property of AuNRs and the suitable glass transition temperature of PLGA short fibers, the hydrogels can not only realize a photothermal anti-bacterial effect, but also photo-triggered on-demand release of DS for anti-inflammatory activity. Furthermore, the sustained release of SDF-1α facilitates endogenous stem cell recruitment. The in vivo experiments demonstrate accelerated healing of infected wounds. The RNA-sequencing analysis reveals that the hydrogel is capable of suppressing the inflammatory response-related pathway. The photo-responsive fiber-embedded hydrogels offer a promising strategy for constructing a photo-triggered programmable therapeutic platform for regenerative medicine. Afiliacje autorów:

However, many existing photothermal materials face limitations such as high production costs or narrow absorption bands, hindering their widespread application. In response to these challenges, researchers have redirected their focus toward harnessing the untapped potential of organic waste-derived and bioderived materials. These materials, with photothermal properties derived from their intrinsic composition or transformative processes, offer a sustainable and cost-effective alternative. This review provides an extended categorization of organic waste-derived and bioderived materials based on their origin. Additionally, we investigate the mechanisms underlying the photothermal properties of these materials. Key findings highlight their high photothermal efficiency and versatility in applications such as water and energy harvesting, desalination, biomedical applications, deicing, waste treatment, and environmental remediation. Through their versatile utilization, they demonstrate immense potential in fostering sustainability and support the transition toward a greener and more resilient future. The authors’ perspective on the challenges and potentials of platforms based on these materials is also included, highlighting their immense potential for real-world implementation.
