In this paper, a biosensors for vapour phase detection of odorant molecules based on Solidly Mounted Resonators (SMRs) is presented. The SMRs were coated with a wild-type bovine odorant-binding protein (wtbOBP), used as sensing layer, and consisted of a piezoelectric aluminium nitride (AlN) film sandwiched between two metal electrodes. An acoustic Bragg… CONTINUE READING
