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

Advanced 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.

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

Advanced 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.
