We report the integration of a nanomechanical sensor consisting of 16 silicon microcantilevers with polydimethylsiloxane (PDMS) microfluidics. For microcantilevers positioned near the bottom of a microfluidic flow channel, a transient differential analyte concentration for the top versus bottom surface of each microcantilever is created when an(More)
We investigate the performance and limitations of silicon microcantilever arrays as biosensors in which receptor molecules are directly tethered to the native oxide without an intermediate metal adhesion layer such as gold. We use our recently developed in-plane photonic microcantilever (PMCL) readout method to simultaneously measure deflection of(More)
We recently developed a new in-plane photonic transduction method for simultaneous readout of microcantilevers in an array on a single chip. Here we describe scale-up of array size to 64 microcantilevers (MCLs) and integration of polydimethylsiloxane (PDMS) microfluidics with chips including multiple MCL arrays. We illustrate biosensing with(More)
