Low-Noise Electronic Readout for High-Throughput, Portable Biomolecular Detection in Microchannel Arrays

Abstract

We have developed a new label-free detection method where specific biomolecules adsorb to the walls of a suspended microchannel resonator, or simply flow through and thereby lower its resonant frequency. The oscillation of the microchannel is measured optically by reflecting a laser beam off the channel surface and detecting its position with a photo… (More)
