Applications of ultrafast lasers in materials processing: fabrication on self-cleaning surfaces and scaffolds for tissue engineering

Materials processing by ultrafast lasers offers several attractive possibilities for micro/nano fabrication applications. Several exciting prospects arise in the context of surface and bulk laser induced modifications. These form the basis for 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. In particular, two examples will be discussed in the following, namely a new approach for the development of superhydrophobic, self cleaning surfaces and the fabrication of functionalized scaffolds, for tissue engineering applications.
