Surface Functionalization

New technologies allowing rapid fabrication of two- and three-dimensional micro-and nano-structures on polymers, metals, ceramics and coatings, open new possibilities in the field of surface engineering. In addition, such technologies do not only offer a route to produce textured surfaces but they also control electrical, chemical and mechanical properties. Therefore, these functionalized surfaces can be used for example in biotechnology, photonics and tribology.
