Abstract

See full text

An apparatus includes a surface acoustic wave (SAW) sensor. The SAW sensor includes a piezoelectric substrate. The SAW sensor also includes first and second interdigitating transistors over the piezoelectric substrate. The first interdigitating transistor is configured to convert an input electrical signal into an acoustic wave. The second interdigitating transistor is configured to convert the acoustic wave into an output electrical signal. The piezoelectric substrate is configured to transport the acoustic wave. The SAW sensor further includes a detection layer over the piezoelectric substrate and positioned at least partially between the first and second interdigitating transistors. The detection layer includes (i) antibodies configured to bind to one or more biological analytes and (ii) a hydrogel layer over the antibodies.
