[Lab-On-A- Chip--systems for biomedical research and diagnosis].

In today's biomedical research and diagnosis, a number of substances and agents have to be checked. Frequently, plastic micro titer plates are used for this purpose as large-area test platforms. For the first time, plastic micro titer plates with 96 identical microfluidic labon-a-chip structures for simultaneous capillary electrophoresis (CE) have now been produced using microtechnical fabrication methods. Such structures are suited for e.g. the separation of biomolecules. In completely sealed microfluidic channel systems, smallest sample volumes can be processed, separated, mixed with other substances, or detected. Due to the small channel dimensions, these microfluidic systems are characterized by very small sample volumes needed.

[Plastic micro-tips for drug delivery].

Removal or exact transfer of minimum substance volumes from reservoirs or microfluidic systems may be accomplished by means of miniaturized tips with integrated through-going capillaries. Applications in biomedical engineering, e.g. for the application of drugs, or in life sciences, e.g. equipping of microarrays, require the use of disposable plastic products for hygienic reasons and reasons of costs. For this purpose, a method to fabricate microtips out of plastic by doublesided molding has been developed at the Forschungszentrum Karlsruhe.
