Abstract
In a mass-sensitive sensor consisting of an acoustic surface wave component on the basis of shear waves, the sensor includes a substrate with an active surface carrying two different layers, one which is a parylene layer of a thickness of between 0.2 and <1.6 μm, which has been produced on the substrate by a vacuum-based deposition method and is capable of generating Love waves and the second layer forms a utilization layer, which interacts with an analyte disposed in a medium contacting the utilization layer.
