A microfluidic cantilever sensor is a nanoscale sensing device that integrates a microcantilever with embedded microfluidic channels to enable highly sensitive detection of physical, chemical, or biological quantities. The cantilever is typically fabricated from silicon or silicon nitride using micro- and nanofabrication techniques. A hollow microfluidic channel runs along the length of the cantilever, allowing liquid samples to flow through it without significantly damping the mechanical motion. The inner surfaces of the channel or the outer surface of the cantilever can be functionalized with
