Plasma Assisted Production of Chemical Nano-Patterns by Nano-Sphere Lithography: Application to Bio-Interfaces
In this work a low-cost parallel technique for creating chemical
nano-patterned surfaces using nano-spheres as masks is presented. This
technique, called nano-sphere lithography, makes use of different steps of
plasma etching and deposition processes, for the creation of polymeric
nano-structures of different chemical functionalities with relevant
applications to bio-interfaces. In this study, the attention is focused on the
plasma processing aspects for the etching of the polymeric masks (colloidal
masks) in order to control the shape and the size of the etched
nano-structures. The bio-functionality of the nano-patterned surfaces has
been proved with a selective immobilization of proteins on the bioactive
spots.
