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. Only the disposable system part comes in contact with the analyte during the measurement process yielding a system suitable for single use applications as required for, e. g., biomedical research.
