Apparatus for focusing a particle in sheath flow and method of manufacturing the same

摘要

An apparatus for focusing a particle in a sheath flow, the apparatus comprising: a sheath fluid inlet for injecting a sheath fluid; a first flow channel for conveying a fluid, wherein the first flow channel extends from the sheath fluid inlet to the fluid outlet and is formed such that a channel extending from the sheath fluid inlet is divided into two subchannels that extend further and are then merged into one channel; and a second flow channel that extends from the sample fluid inlet to the sample fluid outlet, wherein the second flow channel is in fluid communication with the first flow channel at the merged channel region through the sample fluid outlet so as to introduce a particle in a sample into a sheath fluid conveyed through the first flow channel.
