Simultaneous operation of a Love wave biosensor at the fundamental frequenc
y and third harmonic, including the optimisation of IDT metallisation thick
ness, has been investigated. Data is presented showing a sequence of deposi
tion and removal of a model mass layer of palmitoyl-oleoyl-sn-glycerophosph
ocholine (POPC) vesicles while frequency hopping between 110 and 330MHz.
