Advanced Healthcare Materials, EarlyView.The DA/VTP‐NBs selectively recognized cardiac ECs damaged by DIC and achieved cell‐level targeted imaging. Then US‐triggered controlled release successfully enabled the release of DAPA within the DA/VTP‐NBs at the site of injury. This precise on‐demand drug release approach amplifies a series of localized therapeutic effects through the mtDNA‐mediated ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

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.
