Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Quantitative Electrochemical DNA Microarray on a Monolith Electrode with Ten Attomolar Sensitivity, 100% Specificity, and Zero Background [PDF]
Circulating microRNA are promising diagnostic and prognostic biomarkers of disease in quantitative blood tests. A label-free, PCR-free, electrochemical microarray technology on a monolith electrode is described, with 10 attomolar (aM) sensitivity and ...

Integrating Vibrio natriegens for Photon Manipulation in Living Lighting Devices
Rationalization of genetic and material engineering tools has enabled the engineering of fluorescent Vibrio natriegens (V. natriegens) to fabricate straightforward, highly emissive and stable V. natriegens‐silicones color filters for the first red‐emitting bacteria‐hybrid light‐emitting diodes. This pinpoints V. natriegens as a high‐performance protein

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Rewriting Polymer Fate via Chemomechanical Coupling
This work introduces a life‐like “living” polymer platform that can grow, degrow, and reprogram its properties after fabrication. By integrating mass transport, reversible polymerization, and controlled catalysis, the material achieves on‐demand changes in size, shape, and mechanical properties.

Harnessing oxygen inhibition as a materials design principle enables the universal fabrication of core–shell microgels with tunable radial crosslinking gradients. This conceptually simple yet highly versatile strategy generates fusible colloidal bioinks that combine structural hierarchy with adaptive porosity.
