High brilliant fiber lasers can be used to drill or join polymer parts for catheters and microfluidic components without degradation and under sterile conditions. For dosing systems and miniaturized drug depots, short-pulse lasers can be used to create pores in the millimeter or even micrometer range. Soft and flexible materials such as polymers as well as brittle materials such as ceramics can be processed using this technique.
In addition, structuring and molding processes can be applied to produce components for minimally invasive surgical and diagnostic solutions based on fundamental biological principles, such as the sensory hairs of insects (bionics). This means threadlike structures that extend outwards can be producedwith a high aspect ratio by casting laser-generated molds. Targeted photochemical functionalization makes it possible for scientists to control both a surface’s wetting and cell adhesion properties.
