The number of potential lithography applications in the field of life science is growing rapidly. Master molds for microfluidic devices require thick resist processing, vertical sidewalls and high aspect ratio. µTAS (micro total analysis systems) combine several microfluidic devices like mixer, filter and pumps on a chip to integrate a total sequence of lab processes. Our direct write lithography systems have enabled our users to create photomasks for such molds or to expose patterns directly into the resist layer, which allows fast prototyping of new devices.
Structured surfaces such as Tissue engineering are of big interest in the bio-medical community. Porous materials, proteins and polymers can be patterned using Direct Write Lithography. Gray scale lithography allows production of 3 dimensional structures on all kind of materials coated with a photosensitive layer. The big advantage of gray scale lithography compared to other technologies is that it can be applied to large areas and be fabricated in a very short period of time.
Structured UV light is used in many biological applications for photo bleaching, un-caging, photo-switching, opto-genetics, light activation and constrained illumination. New biochips for artificial gene expression systems require a photolithographic step at submicron resolution to immobilize bio-molecules. The µPG platform fulfills all requirements for those applications. A special µPG optics module which can be connected to the optical port of standard microscopes is available on request.
