主权项

1. A microfluidic device for the detection of a target analyte in a fluid sample, said device comprising a solid support member comprising:
a) a sample inlet port; b) a configuration of electrodes for electrokinetic movement of said sample on said solid support member upon application of a voltage; and c) a detection chamber comprising a plurality of detection electrodes positioned in said detection chamber, each comprising a binding ligand and a self assembled monolayer, wherein said detection chamber is in fluid connection to said sample inlet port;wherein said electrokinetic movement is electroosmotic movement or electrohydrodynamic movement.
