Abstract :
Love wave biosensor operating at 440 MHz was developed for simultaneous detection of anti-DNP-KLH IgG in a single sensor. The developed sensor was composed of surface acoustic wave (SAW) reflective delay lines structured by interdigital transducer (IDT) and shorted grating reflectors, a waveguide layer, and two sensitive films. Two mass loading effects caused by two different IgG concentrations were simultaneously measured in a single sensor. The evaluated sensitivities from the first and second sensitive film were 167.9°/μg/ml and 44.8°/μg/ml, respectively.
