Abstract: A device and method for use in capturing a substance in a liquid, by feeding the liquid through a capturing device including: a lateral capillary flow matrix and a capturing matrix in fluid communication with the lateral capillary flow matrix so as to produce two lateral flows sufficient to impart transverse oscillations to the lateral flow in the capturing matrix, such oscillations driving the liquid into the interior of the capturing matrix thereby exposing its interior to the liquid.

Abstract: A capturing device (20) and method for use in capturing a substance in a liquid, by feeding the liquid through a capturing device (20) including: a lateral capillary flow matrix (13) and a capturing matrix (26) in fluid communication with the lateral capillary flow matrix (13) such as to produce a lateral capillary flow in the capturing matrix having a lower velocity than that in the lateral capillary flow matrix. This produces by the Bernoulli effect, a lower pressure with respect to the two lateral flows sufficient to impart transverse oscillations to the lateral flow in the capturing matrix, such oscillations driving the liquid into the interior of the capturing matrix thereby exposing its interior, rather than merely a surface thereof, to the liquid. In the described preferred embodiments, the capturing device is a biological assay device, and each substance in the liquid to be captured in the capture zone of the capturing matrix is a biological substance.

Abstract: Disclosed is a lateral flow capillary device and uses thereof comprising a unipath capillary flow matrix and a plurality of reservoirs each in fluid communication with the capillary flow matrix. The device includes one or more pressure delivery systems configured to urge capillary flow matrix toward a portion of the housing in which it resides, such that a substantially uniform pressure is applied over a portion of the capillary flow matrix.

Abstract: Disclosed is a lateral flow capillary device and uses thereof comprising a unipath bibulous capillary flow matrix and at least two reservoirs each in fluid communication with the capillary flow matrix wherein a reservoir contacts the capillary flow matrix through a passage having a rim pressing the matrix. The pressure that the rim applies on the matrix prevents leakage of liquids out of the capillary flow matrix at the reservoir/matrix interface, allowing accurate sequential draining of liquid from the reservoirs.
