MICROFLUIDIC DEVICE WITH LOW-VOLUME HYBRIDIZATION CHAMBERS FOR ELECTROCHEMILUMINESCENT DETECTION OF TARGET SEQUENCES

摘要

A microfluidic device for detecting target nucleic acid sequences in a sample, the microfluidic device having an array of hybridization chambers, each containing electrochemiluminescent (ECL) probes for hybridization with the target nucleic acid sequences, and electrode pairs for receiving an electrical pulse, the ECL probes being configured to emit a photon of light when hybridized with one of the nucleic acid targets and activated by one of the electrodes, wherein, the hybridization chambers each have a volume less than 900000 cubic microns.
