Abstract
Gravimetric sensors based on shear-mode resonators are suitable for in-liquid detection of biological species because their quality factors barely decrease during in-liquid operation. However, we have found that in the particular case of large ligands, such as bacteria, the transmission of the surface movement to them appears to be more efficient when movement takes place normal to the surface (longitudinal modes) instead of to parallel to it (shear modes). In this work, we succeeded in detecting bacteria with AlN-based bulk acoustic wave solidly mounted resonators operating in longitudinal modes at 2 GHz that we were unable to detect with shear modes
