Printing and Rerouting of Elastic and Protease Responsive Shape Memory Hydrogel Filaments

Advanced Healthcare Materials, EarlyView.
A biofabrication strategy, Rerouting of Free‐Floating Suspended Hydrogel Filaments (REFRESH), is developed enabling the printing of highly elastic, reconfigurable protease‐responsive hydrogel filaments with shape memory properties. The filaments can be manually braided, knotted, and rerouted to create intricate cell‐laden 3D architectures, expanding ...

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.
