Abstract Chronic wounds are that difficult to heal or do not follow the normal healing process. These include pressure ulcers, diabetic venous and arterial incomplete ulcers. Unlike acute wounds, chronic often even heal. Its pathogenesis involves many factors; bacterial infection is main cause of wound. With increase in population aging, incidence has become a critical issue current medical health field. Management faced with problems long treatment time, difficulty, high cost, repeated attacks disability rate, which seriously threaten patients' ability take care themselves life heavy burden individuals, families society. Over past few years, development antibacterial hydrogels for infections received lot attention. Since only have mechanical properties hydrogels, biocompatibility adjustable functional structure, but also excellent properties, they may be an ideal dressing solve problem wound healing. This article introduces types their characteristics, challenges treating wounds. It classifies antimicrobial based on modes further discusses advancements smart along benefits obstacles using explores directions management.

High Strength, Strain, and Resilience of Gold Nanoparticle Reinforced Eutectogels for Multifunctional Sensors

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 20, 2025

Abstract Eutectogels with inherent ionic conductivity, mechanical flexibility, environment resistance, and cost‐effectiveness have garnered considerable attention for the development of wearable devices. However, existing eutectogels rarely achieve a balance between strength, strain, resilience, which are critical indicators reliability in flexible electronics. Herein, poly(sodium styrenesulfonate) (PSS)‐modified gold nanoparticles (AuNPs) eutectic solvents synthesized, PSS‐AuNP reinforced polyacrylic acid/polyvinylpyrrolidone (SAu‐PAA/PVP) eutectogel is successfully prepared. Through coordination AuNPs PAA/PVP polymer chains, SAu‐PAA/PVP exhibits significantly enhanced tensile strain (946%), strength (3.50 MPa), resilience (85.3%). The high‐performance was demonstrated as sensor sensitive to temperature, provided near‐infrared sensing capabilities. Furthermore, inherits benefits ES, including anti‐drying anti‐freezing properties (−77 °C). Moreover, microstructured using simple molding method, resulting hierarchical pyramid functions dielectric layer pressure sensor. This high sensitivity (37.11 kPa −1 ), low detection limit (1 Pa), fast response rate (36/54 ms), excellent reproducibility over 5000 cycles, making them reliable durable detecting small vibrations, potential applications precision machinery, aerospace, buildings.

Solvation Chemistry Enables Eutectogels with Ultrahigh Autofluorescence, Toughness, and Adhesion under Extreme Environments

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 26, 2024

Abstract Compared to conventional gels, eutectogels encompassing deep eutectic solvents (DESs) circumvent the shortboards including poor temperature resistance, high cost, and undesired toxicity. However, existing suffer weak intra‐ interchain interactions, which culminates in vanishing autofluorescence, mechanic feeble adhesion. Although myriad strategies have been proposed boost polymer/polymer interactions within processes are time‐consuming, not suitable for mass production or emergent deployment. Herein, deal with it, a facile solvation chemistry is leveraged build dynamic rigid network via incorporating active polymer backbones DESs. Within these eutectogels, DESs play magnet‐like role, physically cluster chains together multiple noncovalent forces, thus intensifying DESs/polymer interactions. This bestows rare autofluorescence unprecedentedly strength, toughness, adhesion among reported analogues, even harsh conditions. Moreover, mechanism of fully scrutinized first time. It believed that this strategy can be easily expanded orchestrations other soft materials.
