Shape-Memory Surface with Dynamically Tunable Nano-Geometry Activated by Body Heat

Shape‐memory surfaces with on‐demand, tunable nanopatterns are developed to observe time dependent changes in cell alignment using temperature‐responsive poly(ϵ‐caprolactone) (PCL) films. Temporary grooved nanopatterns are easily programmed on the films and triggered to transition quickly to permane...

Description
Summary:	Shape‐memory surfaces with on‐demand, tunable nanopatterns are developed to observe time dependent changes in cell alignment using temperature‐responsive poly(ϵ‐caprolactone) (PCL) films. Temporary grooved nanopatterns are easily programmed on the films and triggered to transition quickly to permanent surface patterns by the application of body heat. A time‐dependent cytoskeleton remodeling is also observed under biologically relevant conditions.
