title: ST Quartz Acoustic Wave Sensors with Sectional Guiding Layers.
abstract: We report the effect of removing a section of guiding layer from the propagation paths of ST-quartz Love wave sensors; this offers the ease of fabrication of a polymer guiding layer whilst retaining the native surface of the quartz which may then be used for the attachment of a sensitizing layer. Data is presented for the rigid and viscous loading, which indicates a small reduction in mass sensitivity compared to a Love wave device. Biosensing capabilities of these discontinuous 'sectional' guiding layer devices are demonstrated using protein adsorption from solution.
