Bioabsorbable Endovascular Adhesive Tape (BEAT) for Improving Vascular Regeneration
Advanced Science, EarlyView.A bioabsorbable endovascular adhesive tape (BEAT) platform based on a hierarchical polyelectrolyte complex is developed to enhance drug delivery in the DCB system. The coating enables rapid transfer to the vessel, provides short‐term mechanical support, and promotes both immediate transfer and long‐term retention of drugs at the lesion site.

Advanced Science, EarlyView.This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.
