A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening

Advanced Materials, EarlyView.
A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.

Remorphable Architectures: Reprogramming Global Bistability through Locally Bistable Metamaterials

Advanced Materials, EarlyView.
Local bistable reconfiguration in mechanical metamaterials is leveraged in globally bistable architectures to enable in situ reprogrammable transition pathways through state flip of individual building blocks. The local‐to‐global correspondence of instabilities empowers soft robotic systems with on‐demand morphing traits, as well as aerospace ...
