Sustainable and Programmable Hydrogels for Bone Regeneration: A Perspective on Green Synthesis and Precision Fabrication

SusMat, EarlyView.
The clinical translation of natural hydrogels is often hindered by a fundamental conflict. Green synthesis prioritizes biosafety through mild and non‐toxic conditions, whereas precision manufacturing demands mechanical robustness and structural fidelity.

Etching-Controlled Growth of Graphene by Chemical Vapor Deposition

, 2017
Graphene growth and etching are reciprocal processes that can reach a dynamic balance during chemical vapor deposition (CVD). Most commonly, the growth of graphene is the dominate process, while the etching of graphene is a recessive process often ...

Electrochemical aptasensors for ultrasensitive multiplexed detection: Towards a new era of precision diagnostics and environmental monitoring

VIEW, EarlyView.
Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.

Chemical etching of silicon assisted by graphene oxide under negative electric bias [PDF]

Chemical etching of silicon assisted by graphene oxide (GO) is attracting attention as a new method to fabricate micro- or nano- structures. GO promotes the reduction of an oxidant, and holes are injected into silicon, resulting in the preferential ...

Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

Advanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Monolithic 3D‐Integrated All‐Solid Ion‐Gated Carbon Nanotube Transistors With Tunable Ionic Conductance for Multi‐Timescale Reservoir Computing

Advanced Materials, Volume 38, Issue 55, 1 October 2026.
A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, Volume 38, Issue 55, 1 October 2026.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Elastomeric 3D‐Printed Microenvironments Enable Nanonewton Force Measurements in Healthy and Diseased Human Pluripotent Stem Cell‐Derived Neuroepithelial Cells

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...
