3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

Advanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Facile Deep Brain Electrode Coating with MXene for Improved Electrode Performance

Advanced Healthcare Materials, EarlyView.
Facile dip‐coating of commercial carbon fiber electrodes with Ti3C2Tx MXene improves electrical conductivity, reduces impedance, and enables single‐neuron recordings in the rat hippocampus over four weeks. The coating maintains biocompatibility, minimizes inflammation, and remains MRI‐compatible.

Biologically Active Implants Prevent Mortality in a Mouse Sepsis Model

Advanced Healthcare Materials, EarlyView.
A modular, triple‐action titanium implant is developed to prevent implant‐associated infections by repelling bacteria, killing pathogens, and enhancing tissue integration. Coatings with phage cocktails targeting P. aeruginosa and S. aureus show significant bacterial reduction and improved survival in a mouse sepsis model.

Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

Advanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.

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 ...
