Abstract
A mixed acrylate-siloxane polymer can be used to create three-dimensional (3D) structures of arbitrary shape via nanolithography. Treatment of such structures with amine (such as diamine) makes them permissive for neuronal cell adhesion and growth without need of additional modification such as poly-lysine (D or L) nor laminin.
