Abstract
In a centrifugal microfluidic device for conducting capture assays, a microfluidic platform rotates in a plane of rotation and has at least one capture surface for immobilizing a target particle of interest in the device. The capture surface oriented so that it is not parallel to the plane of rotation of the device and is positionally fixed in the device during operation of the device. The centrifugal force arising from rotation of the device forces the target particles against the capture surface. Capture efficiency is independent of the rate of flow of the fluid and independent of the rate of rotation of the microfluidic platform.
