Development of a combined surface plasmon resonance/surface acoustic wave device for the characterization of biomolecules [PDF]

open access: yes, 2009
It is known that acoustic sensor devices, if operated in liquid phase, are sensitive not just to the mass of the analyte but also to various other parameters, such as size, shape, charge and elastic constants of the analyte as well as bound and viscously
