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

Advanced 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.
