Sheath-flow forming by using twisted micro-channel

We developed a twisted micro-channel in order to form a sheath flow in an integrated micro-fluidic chip. The new device has a central straight channel and two parts of 2-dimensional merging channel. It is twisted by 90 degree in between the first part and the second part. We applied the unique mater...

Zusammenfassung:We developed a twisted micro-channel in order to form a sheath flow in an integrated micro-fluidic chip. The new device has a central straight channel and two parts of 2-dimensional merging channel. It is twisted by 90 degree in between the first part and the second part. We applied the unique material property of polydimetylsiloxane (PDMS), that is elasticity; "easily bent and twisted". The micro-channel configuration (width, length etc.) were designed to form an isotropic focusing flow. Distribution of particle's velocity in the section of the micro-channel down the junction points showed sheath flow forming.
