Materials processing by ultrafast lasers offers several attractive possibilities for micro/nano materials processing. Prospects arising will be discussed in the context of surface and in bulk laser induced modifications. In particular, examples of diverse applications including the development and functionalization of laser engineered surfaces, the laser transfer of biomolecules and the functionalization of 3D structures constructed by multiphoton stereolithography will be presented. Finally, the removal of molecular substrates by ultrafast laser ablation will be discussed with emphasis placed on assessing the photochemical changes induced in the remaining bulk material; these are particularly important when it comes to applying lasers in fine art conservation.
