Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced 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 ...

Rapid Glass‐Substrate Digital Light 3D Printing Enables Anatomically Accurate Stroke Patient‐Specific Carotid Artery‐on‐Chips for Personalized Thrombosis Investigation

open access: yesAdvanced Materials, EarlyView.
A rapid glass‐substrate 3D microfabrication method creates anatomically accurate carotid artery‐on‐a‐chip models from stroke patient scans in 2 h. These miniaturized devices replicate patient‐specific blood vessel geometry and flow patterns, enabling real‐time imaging of clot formation under controlled injury.
