Artery‐on‐Chip Demonstrates Mechanical and Functional Features of Healthy and Diseased Living Smooth Muscle Tissue

Advanced Functional Materials, EarlyView.
This article details the development of an artery‐on‐chip platform for in vitro arterial disease modeling and therapeutic discovery. It describes the fabrication of a fibrin biomaterial scaffold seeded with iPSC‐derived smooth muscle and endothelial cells, mimicking native artery properties. Two genetic disease models showcase the platform's ability to

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Low‐Fraction Irregular Inclusions Trigger Large Compression Stiffening in Biopolymer Hydrogels

Advanced Functional Materials, EarlyView.
Irregular inclusions at low filler fractions trigger large compression stiffening in biopolymer hydrogels. By promoting contact‐network formation under compression, these inclusions induce non‐affine rearrangements, stretch surrounding fibers, and provide parallel load‐bearing pathways.

Three‐Dimensional Biomimetic Aerogel Conduits with Electro‐Ionic‐Immune Coupling Reverse the Pathological Cascade of Spinal Cord Injury

Advanced Functional Materials, EarlyView.
A biomimetic aerogel conduit was engineered from a nanofiber of gelatin/poly(l‐lactic acid) doped with polypyrrole nanoparticles, integrated with tannic acid and Mg2+. This “electro‐ionic‐immune” strategy mimicked spinal cord properties, reduced calcium overload, inflammation, oxidative damage, promoted neural stem cell differentiation, suppressed ...

3D‐Printable, Biodegradable, and Conductive/Piezoionic Hydrogel ‘E‐Skin’ With Robust Antibacterial Properties for Wound Healing and Wireless Human‐Machine Interface Sensing

Advanced Functional Materials, EarlyView.
A multifunctional MXene‐integrated GelMA/alginate hydrogel reinforced with TEMPO‐modified nanocellulose is engineered via dynamic covalent, ionic, and hydrogen bonding. The resulting piezoelectric, adhesive, antimicrobial, and 3D‐printable patch enables motion sensing and accelerates wound healing by promoting keratinocyte migration and collagen ...
