The quest for efficient harvesting of solar radiation is one of the major areas of research in the renewable energy field. Through different photonic architectures it is possible to augment the optical absorption by trapping light within thin and ultra-thin films, the latter being desirable to decrease costs and efficiently extract the photogenerated charge carriers. Engineering the absorbing material at the nanoscale indeed leads to interferences that can significantly increase light absorption [1].

A new method for preparing 3D scaffolds for tissue engineering applications with highly controlled micro and nanotopography have been developed. A combination of UV and electron beam lithography was employed for master fabrication and nanoimprint lithography for the preparation of the 3D polymeric scaffolds.
