Microfluidic in Polymer

Microfluidics deals with handling small amounts of fluids e.g. for point-of-care applications. The miniaturization of analytical systems leads to major improvements like shortened analysis times, less reagent consumption or higher mobility. Therefore so called lab-on-chips are gaining more and more importance.


Main markets for microfluidic systems are

Point-of-Care and Molecular Diagnostics
Life Science
Food and Environmental Analysis

Microfluidic in plastics

Since the first microfluidic devices in the early 1990s polymers have found their way into lab-on-chip applications. Compared to glass polymers have the advantage of low-cost mass production possibilities. Plastic disposables for diagnostic use can reduce cross-contamination issues and bring the lab to the patient. Some polymers like PMMA or polystyrene are traditional materials for labware and offer good biocompatibility.

CDA’s microfluidic

With its strong background in optical media production CDA is a reliable partner when it comes to injection moulding of microstructured surfaces. Based on one master high volumes are manufactured with constant quality. We offer in-house services like mastering, moulding or singulation. Working with different mastering techniques typical structure sizes for microfluidic applications are replicated. By injection moulding as well as compression moulding structures in the sub-µm range can be realized. The features range from complex channel systems over pillars and wells to microstructured surfaces for cell culturing. Depending on the application different polymers like polycarbonate, PMMA, COC, COP, etc. can be used to obtain optical quality or biocompatibility. 

Combining Technologies

One important aspect in developing microfunctional solutions is the integration of different smart features in one device. Examples thereof are electrodes in fluidic channels or optical elements in point-of-care devices. CDA covers the areas of microfluidics, microoptics and printed electronics and brings them together in unique products. For example we print conductive paths, electrodes and passive elements or integrate optical components like beam shapers or diffractive lenses into the fluidic system.

Working with CDA

Whether you want to test your ideas, have your first prototype at hand or are looking for mass manufacturing CDA could be the right partner for you. With flexible production processes we can support you in each phase of your way. We offer customized solutions that fit the needs of your project.
