A Highly Adaptable Hydrogen Bond Re‐Orientation (HyBRO) Strategy for Multiscale Vasculature Fabrication

open access: yesAdvanced Materials, EarlyView.
A novel hydrogen bond re‐orientation (HyBRO) strategy enables three‐dimensional (3D) printing of vascular microchannel networks with high accuracy. By switching sacrificial material interactions with nonsolvents, HyBRO prevents swelling and deformation, enabling accurate hierarchical channels spanning a tenfold size range.
