Biocompatible PVDF Nanofibers with Embedded Magnetite Nanodiscs Enable Wireless Magnetoelectric Stimulation in Premotor Cortex

open access: yesAdvanced Healthcare Materials, EarlyView.
Flexible, biocompatible PVDF nanofibers embedded with magnetite nanodiscs enable wireless magnetoelectric neuromodulation. Shape anisotropy of the nanodiscs facilitates magnetostrictive strain transfer under alternating magnetic fields, allowing activation of neurons in vitro and behavioral modulation in vivo, without requiring rigid implants or ...

Biomimetic Scaffolds with Dual Gradients of Biological Effectors for Tendon‐to‐Bone Repair

open access: yesAdvanced Healthcare Materials, EarlyView.
The authors have developed a biomimetic scaffold with dual gradients through a diffusion‐driven method. The scaffold features funnel‐shaped microchannels for cell infiltration, while the dual gradients synergetically induce the graded differentiation of mesenchymal stem cells into osteoblasts, chondrocytes, and tenocytes, allowing for a seamless ...

Symmetry is the Key to the Design of Reticular Frameworks

open access: yesAdvanced Materials, EarlyView.
Computational prediction of the molecular structure of porous materials, particularly reticular framework materials such as MOFs and COFs, remains a significant challenge. Considering the symmetry of the building blocks that form the desired material, and a similarity score with existing experimentally characterized structures, helps identify promising

A Highly Adaptable Hydrogen Bond Re‐Orientation (HyBRO) Strategy for Multiscale Vasculature Fabrication

open access: yesAdvanced Materials, EarlyView.
A novel hydrogen bond re‐orientation (HyBRO) strategy enables three‐dimensional (3D) printing of vascular microchannel networks with high accuracy. By switching sacrificial material interactions with nonsolvents, HyBRO prevents swelling and deformation, enabling accurate hierarchical channels spanning a tenfold size range.

Selective Lipolysis by Photoactivation of Chaperone‐Mediated Autophagy Using Adipocyte Membrane‐Coated Nanoparticle in Hydrogel

open access: yesAdvanced Materials, EarlyView.
Adipocyte membrane‐coated nanoparticles loaded with rosiglitazone in hydrogel offer an alternative approach to conventional obesity treatments. This system selectively targets adipocytes, inducing lipolysis by activating chaperone‐mediated autophagy through mild photothermal stimulation.
