Abstract
Biosensor apparatus and associated method for detecting a target material using a vibrating resonator having a surface that operably interacts with the target material. A detector is in electrical communication with a sensor, the sensor comprising a first paddle assembly connected to a second paddle assembly, the first paddle assembly having at least one microbalance sensing resonator proximate a proximal end and at least one sensing electrical contact proximate a distal end in electrical communication with the sensing resonator. The at least one sensing resonator has a target coating for operably interacting with the target material, and the second paddle assembly has a microbalance reference resonator proximate the proximal end and at least one reference electrical contact proximate the distal end in electrical communication with the reference resonator.
