In this article we propose a novel label-free chemical/biochemical sensing device based on a waveguide resonator with an integrated microfluidic channel. This device is intended for the characterisation and detection of cells and various chemical substances from within a variety of micro-litre test samples. This paper outlines the design of the prototype device and describes the fabrication of the microfluidic network and microwave resonator. Initial testing of the prototype at X-band is examined with promising results. Finally, we propose a Low Temperature Co-fired Ceramic (LTCC) integration scheme for the miniaturization of the device for use in the THz regime.
