Abstract:
1. A centrifugal microfluidic device comprising: a rotatable platform; a sample chamber which is disposed in the rotatable platform and houses a fluid sample; a distribution channel connected to an outlet of the sample chamber; a plurality of non-vented reaction chambers which are disposed in the rotatable platform outside of the distribution channel in the radial direction; and a plurality of inlet channels which connect the distribution channel with the reaction chambers; wherein the fluid sample housed in the sample chamber is distributed to the plurality of non-vented reaction chambers through the distribution channel by a centrifugal force due to a rotation of the rotatable platform, and wherein the distribution channel comprises: a first section which is connected to an outlet of the sample chamber and extends in a radial direction of the rotatable platform, and a second section which extends from the first section in a circumferential direction of the rotatable platform, and wherein a cross section of the distribution channel is substantially the same throughout the first and second sections such that a fluid resistance is substantially the same throughout the first and second sections.
