Severe skin injuries such as burns and chronic wounds are a subject of interest in the medical field, they require much attention. These types susceptible to serious complications, which can worsen health patients reduce their quality life. Hydrogels have emerged innovative wound dressings for treating acute wounds, including burns, diabetic foot ulcers, venous leg pressure ulcers. polymeric networks provide moist environment, promote cellular migration, offer antimicrobial properties, being recognized superior conventional dressings. This review aims explore recent advancements hydrogel-based dressings, emphasizing state-of-the-art technologies used this purpose trend achieving personalized therapeutic approaches. Despite promising vitro vivo findings described review, further clinical validation large-scale manufacturing optimizations required widespread adoption.

Abstract Diabetes significantly impairs the body's wound‐healing capabilities, leading to chronic, infection‐prone wounds. These wounds are characterized by hyperglycemia, inflammation, hypoxia, variable pH levels, increased matrix metalloproteinase activity, oxidative stress, and bacterial colonization. complex conditions complicate effective wound management, prompting development of advanced diabetic care strategies that exploit specific characteristics such as acidic pH, high glucose stress trigger controlled drug release, thereby enhancing therapeutic effects dressings. Among solutions, hydrogels emerge promising due their stimuli‐responsive nature, making them highly for managing these The latest advancements in mono/multi‐stimuli‐responsive smart showcase superiority potential healthcare materials, highlighted relevant case studies. However, traditional dressings fall short meeting nuanced needs wounds, adjustable adhesion, easy removal, real‐time status monitoring, dynamic release adjustment according wound's conditions. Responsive represent a significant leap forward proficient sensing responding environment, offering more targeted approach treatment. This review highlights recent dressing, delivery, emphasizing role improving healing. It addresses ongoing challenges future directions, aiming guide clinical adoption.

Rapid rewarming is the standard and most common strategy for treating frostbite. Due to freezing susceptibility lack of thermal effects, traditional therapeutic hydrogels are not suitable being directly applied frostbite therapy in cold conditions. Contrastively, antifreezing photothermal that apt freeze capable wounds deemed hold great application potential such therapy. Nevertheless, these have rarely been researched. Herein, using glycerol as cryoprotectant polydopamine nanoparticles (PDA NPs) agent, a novel pullulan-based organohydrogel (CPG-PDA organohydrogel) was successfully developed treat first time. The CPG-PDA formed through 1-ethyl-3-(3-(dimethylamino)propyl)carbodiimide hydrochloride (EDC·HCl)-mediated esterification reactions found possess certain mechanical stability, shear-thinning behaviors (injectability), excellent properties, superb vitro vivo performances, outstanding cytocompatibility hemocompatibility. Most noticeably, coating observed significantly accelerate healing rats. opined be promising platform direct treatment environment would open new avenue design strategies
