Abstract

A fluidic device and a method of preventing isolation material from bleed-out therein is described herein. The fluidic device includes a bulk acoustic wave resonator structure defining at least one surface area region on which a functionalization material is disposed and the resonator structure includes a repelling area. The fluidic device also includes isolation material disposed on the resonator structure and away from the at least one surface area region. The repelling area is configured to prevent the isolation material from extending into the at least one surface area region. Further, an electronic board may be operably attached to the resonator structure and the isolation material may be disposed in a gap therebetween to electrically isolate electrical contacts and form a fluidic channel.
