Abstract

We describe the fabrication and electrical testing of Suspended Microchannel Resonators (SMRs) with integrated piezoresistive readout. The SMR incorporates fluidic channels inside a resonant cantilever thereby eliminating viscous damping from the solution. Previously, this concept has been used to measure mass in fluid with a resolution of 1 femtogram (1 Hz bandwidth) [1]. Piezoresistive readout eliminates the need for external optics, and we anticipate that the integrated device can be used in a variety of biomolecular and cell-based assays for point-of-use applications.
