Paper Abstract

In recent years there has been an increasing demand for functional integration in microfluidic devices. This integration often requires the use of different materials in order to generate the demanded performance. Typical examples for such integrated functionalities are on-chip valves or areas used for sealing one component against another, e.g. a microfluidic manifold against a sensor chip. Such functionalities have been described in the literature mainly by using elastomeric materials such as PDMS. However this material suffers from the lack of suitable high-volume manufacturing processes and its high material cost. For production of such hybrid material devices, two-component injection molding can prove to be a suitable microfabrication method. In our paper we will present several examples for such two-component injection molded microfluidic components such as a mechanical turning valve, microfluidic chips with gasketing structures and chips with plug seals to close a fluidic port.
