We investigate the performance of solidly mounted resonators based on Ir/tilted-AlN/Ir piezoelectric stacks as biosensors. These films are deposited by varying the pressure, the cathode power and the tem- perature of a two-step process based on depos

Publikováno v: Sensors and Actuators B: Chemical. 222:688-692

Gravimetric biosensors based on piezoelectric resonators have their active area just atop an electrical contact. Sometimes both contacts are located on the same surface (coplanar electrodes). The use of bio-buffers with high ionic content makes often

In this communication we present the integration of graphene on the top electrode of solidly mounted resonators based on piezoelectric AlN thin films for gravimetric sensor applications. Because its particular chemical structure, graphene shows great

Shear mode solidly mounted resonators (SMRs) are fabricated using an inclined c-axis ZnO grown on a rough Al electrode. The roughness of the Al surface is controlled by changing the substrate temperature during the deposition process to promote the g

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 ligand

Lauryl gallate (antioxidant food additive E-312) prevents the formation of dimethylbenzanthracene-induced skin tumours in mice, and kills, selectively, tumoral cells on established tumours. This results in total remission, after topical application o
