Abstract
Devices for use in extracting an analyte of interest from a sample are described. In one embodiment, a device is comprised of a first plurality of chambers, where one or more chambers in the plurality of chambers has a deep end and a shallow end with a depth d. A channel disposed between at least two adjacent chambers in the plurality of chambers has a depth greater than d. The dimensions of the chamber and channel provide control of fluid movement in the device, particularly when introducing fluid into the device for its use and during use of the device.
