Mandibular Implants: A Metamaterial‐Based Approach to Reducing Stress Shielding

open access: yesAdvanced Healthcare Materials, EarlyView.
Metamaterial mandibular implants offer a novel approach to reducing stress shielding and enhancing biomechanical stimulation. This study compares a gyroid‐based metamaterial plate to a solid titanium plate using photoelasticity and finite element analysis.

Biofunctionalization of ADA‐GEL Hydrogels Based on the Degree of Cross‐Linking and Polymer Concentration Improves Angiogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
The biocompatibility of alginate dialdehyde (ADA) and gelatin (GEL) hydrogels cross‐linked with human transglutaminase (hTG) is demonstrated in vivo with a high degree of stability and angiogenic potential. The additional enzymatic cross‐linker hTG and the increased concentration improve stability and angiogenic potential. The X‐ray microscopy (XRM) is

Hydrogel‐Impregnated Robust Interlocking Nano Connector (HiRINC) for Noninvasive Anti‐Migration of Esophageal Stent

open access: yesAdvanced Materials, EarlyView.
The development of hydrogel‐impregnated robust interlocking nano connector (HiRINC) aims to address stent migration by improving tissue adhesion and reducing mechanical mismatch in self‐expandable metallic stents (SEMSs). The network‐like porous layer of HiRINC enhances adhesion and energy dissipation, demonstrates through ex vivo and in vivo tests ...

Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

open access: yesAdvanced Materials, EarlyView.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.
