Abstract: Assay devices and method for the detection of the presence or amount of biological material, analyte(s), or microorganism(s) in a sample. The assay devices generally have a flat horizontal surface that is divided into a plurality of recessed wells; or one or more surfaces with reagent island(s) immobilized thereon. Each well or reagent island is formed of a suitable material, and is adapted in shape and size to hold an aliquot within the well or reagent island by surface tension. The devices have at least one reagent provided within the wells or reagent islands. The assay method includes the steps of liquefying the sample (if necessary) and distributing the liquefied sample over the surface of the assay device. Any excess liquid from the liquefied sample is drained from the surface of the device. The method then involves incubating the assay device until the presence or amount of the biological material, analyte, or microorganism is determined.

Abstract: The invention provides devices and methods for rapid quantification of microorganisms and cells. In one embodiment, the devices comprise a container having an upper compartment and a lower compartment, wherein the upper compartment is connected to a passage through which a fluid sample can flow and enter the upper compartment, and wherein the lower compartment is connected to a passage through which a fluid sample can flow and exit the lower compartment; a mounting structure upon which a filter can be positioned; a filter, wherein the filter separates the upper compartment from the lower compartment, wherein the filter comprises a chromogen; a first template covering the filter, wherein the first template comprises a predetermined number of holes through which a liquid sample can flow through to discrete locations on the filter; and an absorbent pad under the filter and in contact with the filter.
