Exploring the Role of Stent Strut Geometry in Cellular Behavior: An In Vitro Chip Model to Understand In‐Stent Restenosis

open access: yesAdvanced Materials Interfaces, EarlyView.
An engineered in vitro platform mimicking stent strut cross‐sectional shapes reveals how geometry influences cell behavior. Sharp‐cornered geometries promote cell proliferation and matrix alignment, while rounded shapes reduce these effects. The findings align with clinical outcomes and suggest intracellular tension as a key driver, offering a ...

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.
