Abstract

A method for analyzing liquid samples may comprise applying a liquid to a cMUT device having a plurality of sensors, drying the plurality of sensors, electronically detecting an agent bound to each of the plurality of sensors, wherein the electrical circuit provides a sensor output responsive to a mechanical resonance frequency of the sensor, wherein the mechanical resonance frequency of the sensor is responsive to the binding of an agent to the functionalized membrane, and determining the mass of the agent bound to each of the plurality of sensors.
