Tapered Pillar Design for High‐Precision Force Readout in Miniaturized Engineered Heart Tissues From Human Pluripotent Stem Cells

Advanced Healthcare Materials, EarlyView.
Engineered heart tissues (EHTs) are a valuable approach in capturing human cardiac physiology and drug responses in vitro. Here, a novel tapered pillar design is developed in an EHT platform to confine tissues in a predefined position‐ at the middle of the pillar height.

Xeno‐Free Biocompatible Peptide‐Based Bioinks Reinforced with Cellulose Nanofibers for 3D Printing

Advanced Healthcare Materials, EarlyView.
A xeno‐free bioink combining self‐assembled peptides and cellulose nanofibers is developed for 3D printing. The bioink forms a non‐cross‐linked 3D scaffold, mimicking the extracellular matrix and supporting over 95% cell viability. This approach offers enhanced biocompatibility and mechanical stability, advancing 3D printing for personalized medicine ...

Miniaturized Wireless tDCS With Concentric Electrodes for Targeted Cortical Stimulation in Freely Moving Mice

Advanced Healthcare Materials, EarlyView.
This study introduces a wireless and miniaturized concentric‐electrode tDCS (CE‐tDCS) system tailored for freely moving mice. The device enables focal and multi‐site cortical stimulation via a lightweight, Bluetooth‐controlled platform. By integrating local neuromodulation with real‐time behavioral analysis, the system provides a robust tool for ...

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Robust pH Sensing Using a Graphene Oxide and Covalent Organic Frameworks Composite for Gastro‐esophageal Reflux Disease Diagnosis

Advanced Healthcare Materials, EarlyView.
A stable composite pH sensor is developed by coating graphene oxide (GO) nanosheets with covalent organic frameworks (COFs) to improve stability and sensitivity in acidic environments. The GO/COFs sensor demonstrates high selectivity, linearity, and biocompatibility, offering a promising strategy for continuous pH monitoring in gastro‐esophageal reflux
