ABSTRACT:
A microfluidic device with a vertical injection aperture is provided. The microfluidic device comprises a separation channel, an injection aperture disposed adjacent to and in fluid communication with the separation channel. The microfluidic device further comprises a semi-permeable filter disposed adjacent to the injection aperture, wherein the filter is configured to preconcentrate a sample in the injection aperture to form a preconcentrated sample plug during an injection operation, and wherein the sample plug flows downwardly from the injection aperture to the separation channel during an electrophoresis operation.
