The influence of surface structuring on surface acoustic wave (SAW) biosensor signals has been investigated. Polymer structures on the sensor surfaces were applied by lithography or by self-assembling of polystyrene microparticles. In first experiments, structured and unstructured sensors led to similar results in a model affinity assay using streptavidin and biotinylated protein. On the other hand,...
In this paper we present a latchable, thermally activated phase change (PC) actuator. The actuator can be controlled using a heating resistor and two pressure sources. Thus several hundred actuators can be driven using a highly integrated platform which allows the individual control of several hundred heating resistors. To optimize the response time of the actuators we analyzed the influence of the...
We will describe the use of an alternative polymer which is suitable for use in microfluidic applications which require the use of harsh chemicals or aggressive solvents. Currently microfluidics systems are mainly manufactured in polydimethylsiloxane (PDMS) due to its ease of use, and the ability to produce monolithic microfluidic valves directly into the same material as the microfluidic chip. However,...
We present an 8-fold biosensor system based on surface acoustic waves (SAW). The single biosensors are individually embedded in polymer housings and combined into a sensor array via a passive microfluidic polymer chip. The latter is set up as the main part of an indirect microfluidic flow injection analysis system which is able to strictly separate the system into reusable and disposable components...
In this paper, we describe a modification of the classical hot embossing process which is capable of producing holes in polymer substrates. Substrates with holes that penetrate the complete height of the substrate have been a technical challenge since the first description of the hot embossing process. However most components as, e. g., microfluidic components targeted for biomedical applications...
