Abstract Open wounds damage the integrity of injured tissues and expose them to bacterial infections. Traditional suturing often lead reinjuring damaged tissues. This delays healing process, especially in presence a infection. A Janus hydrogel adhesive with bio‐adhesion multi‐mode disinfection (BAMD) capabilities (a BAMD hydrogel) is developed using spin‐coating which can serve as an alternative traditional sutures. The organic–inorganic hybrid combination Chinese‐medicine organic small molecule rhein (Rhe) graphene oxide (GO) endows dual‐mode antibacterial activity driven by photodynamic (PD) photothermal (PT) effects including short‐term rapid (15‐min irradiation, 99.95% bactericidal rate) long‐term action absence light (100% rate after 6 h dark incubation). vivo results demonstrated 97.25% against MRSA. Throughout wound recovery effectively reduced inflammation promoted tissue healing. versatile strategy offers new insights into preventing postoperative adhesion sealing repairing large‐scale damage.

Abstract Stringent environmental policies and sustainability targets are driving the adoption of lightweight materials in high‐performance transportation defense sectors. Inspired by nature's unparalleled engineering, this work introduces butterfly‐inspired hybrid composites that emulate multifunctional performance natural architectures. Specifically, these reinforced with hierarchical fibrous assemblies comprised nano‐sized graphene nanoplatelets covalently bonded onto micro‐sized glass fibers, emulating architecture butterfly legs. Additionally, sandwich‐structured designed to mimic alternating rigid porous layered scales wings, featuring a foamed composite core sandwiched between solid skins, leading superior mechanical thermal management performance. Compared current industrial substitute for metallic structural components, tailorable achieve improvements up 32%, 36%, 116% specific tensile strength, flexural impact respectively, as well 66% insulation 62% performance, 38% weight reduction. These advancements stem from detailed structure‐property designs, spanning across multiple length‐scales, formulating fundamental understanding how tune meet stringent requirements. Ultimately, cost‐effective, industry‐ready produce lightweight, components showcase potential biomimicry advancing sustainable engineering solutions.

ConspectusLiquid crystal elastomer fibers (LCEFs) are reversible artificial muscles capable of stimuli-responsive functions, making them promising competitors for ideal soft actuators. These remarkable actuation properties depend strongly on their mechanical properties, such as elastic modulus and breaking stress. It is necessary to strengthen the LCEF meet demands advanced applications. However, despite significant progress in LCEFs, there currently no Account systematically summarizing analyzing strategies adopted enhancing properties. The intuitive variations among different enhancement further call investigations into how choose most suitable ones based specific situations. In this Account, first time, we summarize existing approaches strengthening LCEF-based muscles, contributing development more robust smarter fibrous muscles.In section, focus latest valuable highlighting need a comprehensive summary various utilized. LCEFs can be tailored through molecular design, physical interactions, fiber integration. adjustment hard/soft segment features, introduction additional microstructures, integration provide opportunities which discussed second section. Subsequently, delve impact preparation methods performance fabricated by spinning alignment techniques exhibited rather This has been engineer novel, stronger, described third Moreover, show that incorporation rigid composite materials via coating doping emerged powerful strategy core-shell structures. Such enhancements also introduce multifunctionality LCE-based enrich structure mechanism, elucidated fourth Finally, conclude with critical analysis challenges prospects hoping pave way construction muscles.

In trauma and surgery, efficient hemorrhage control is crucial to avert fatal blood loss increase the likelihood of survival. There a significant demand for novel biomaterials capable promptly effectively managing bleeding. This study aimed develop flexible biocomposite fibrous scaffolds with an electrospinning technique using silk fibroin (SF) indocyanine green (ICG). The FDA-approved ICG dye has unique photothermal properties. water permeability, degradability, biocompatibility Bombyx mori cocoon-derived SF make it promising biomedical applications. While as-spun SF-ICG fibers were dissolvable in water, ethanol vapor treatment (EVT) induced secondary structural changes promote β-sheet formation. resulted significantly improved aqueous stability mechanical strength fibers, thereby increasing their fluid uptake capability. enhanced interaction prevented leaching from composite enabling them generate heat under NIR irradiation due ICG's Our results showed that 0.4% matrix can 473% water. When was replaced by bovine blood, 25 s complete coagulation. However, pure did not have same effect. Additionally, successfully stopped flow vitro model mimicked damaged vessel. breakthrough offers biotextile platform poised enhance patient outcomes across various medical scenarios, representing milestone functional biomaterials.
