Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

open access: yesAdvanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Atomic‐Level Ionic Displacement Polarization Enhanced Piezocatalytic Hydrogen Evolution in Covalent Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
Two isomorphic COFs were synthesized and compared, including an amphoteric COF (SQ‐TAPT) and a neutral COF (PDA‐TAPT). The ionic bonds in SQ‐TAPT introduce more Born effective charges, thereby enhancing its ionic displacement polarization. Experimental and theoretical calculations demonstrated that SQ‐TAPT exhibited higher polarity and stronger ...

Injectable Dual‐Crosslinked Poly(oligo(Ethylene Glycol) Methacrylate) Hydrogels Inspired by Mussel Adhesion for Cutaneous Wound Healing and Functional Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Injectable POEGMA‐DA hydrogels, dual‐crosslinked via dopamine self‐polymerization and dynamic hydrazone bonds, provide a safer alternative to invasive wound closure methods and toxic bioadhesives. Mimicking skin‐like mechanics, they achieve effective tissue adhesion for acute dermal wounds, supporting improved healing outcomes, including reducing ...

Synthetic Cell‐Based Tissues for Bottom‐Up Assembly of Artificial Lymphatic Organs

open access: yesAdvanced Healthcare Materials, EarlyView.
Synthetic cells have emerged as a novel biomimetic approach for fundamental research and therapeutic interventions. T cell activating synthetic cells are able to form 3D tissue‐like structures by self‐assembly into lymphatic bottom‐up tissues (lymphBUT) with tunable biochemical and biomechanical functionalities as well as metabolic activity are ...
