Surface acoustic wave sensors: From design to chemical and biological applications

Surface acoustic wave (SAW) sensors are versatile devices, as they can be used to sensing temperature, pressure, strain, torque or mass. Theses abilities can be extended to chemical and biological investigations by suitable functionalisation of the sensing area. Depending on the intended application, the sensitive layer which must to specifically detect the chemical or the biological analyt of interest, may be: single strand DNA, antibody, antigen proteins, self-assembled monolayers, molecularly or ionic imprinted polymers,… This presentation will focus on some chemical and biological applications we have developed, to highlight the potential of this kind of sensors.
