The goal of this work is to develop an original and high performance hybrid lab-on-a-chip, coupling actuators and biosensors for the active control and broad range characterization of biofluids samples. These biofluids will be controlled (moved and mixed) actively by Rayleigh-Surface Acoustic Wave (R-SAW) and analysed in real-time by combining Love-SAW (L-SAW) and Surface Plasmon Resonance (SPR) technologies. A microfluidic chamber and specific transducer were designed for this application to

... teract efficiently with the liquid sample entrapped in the chamber and to detect modifications of its physical properties such as viscosity. AT-cut quartz and LiNbO 3 36Y-X substrates were used to generate both Rayleigh and Shear-Horizontal waves and ZnO material as guiding layer. The whole system has proven is full efficiency to interact with the fluid and to detect the signal perturbations with no significant loss compared with the measurements carried out with a probe station.
