Focus/Key Topic:


Microfluidics start where the bare eye reaches its limits. At this scale, in which pico- and nanolitres are normal volumes, physical effects become relevant that would otherwise be negligible. As a result, mixing, flows and other phenomena can be observed.

In photocatalytic systems these phenomena can be influenced by an external light source. For example, current 3D printers use UV light to trigger a photocatalytic reaction to produce three-dimensional structures. However, most of the existing systems are designed for the production of parts on a millimeter to centimeter scale and can therefore not be used for the illumination of microfluidic channels.

In this thesis a projection lithograph for focused exposure in microfluidic chips will be designed and tested.
