Light-induced dynamically tunable micropatterned surface for the regulation of the endothelial cell alignment

The surface topography has a great effect on the behaviour of adherent cells. We report an efficient method to prepare shape memory surfaces with dynamically changed micropatterns, which can be induced by near-infrared (NIR) light by varying the power density. After polydopamine (PDA) was coated on the cross-linked polyethylene glycol-poly(ε-caprolactone), the surface temperature increases by 40°C...
