Disclosed is a method for determining the presence and/or amount Oran analyte of interest in a liquid sample comprising the steps of: contacting the liquid sample suspected of containing analyte with a gas generating means (eg. catalase and peracid or peroxygen compound), which gas generating means forms a gas dependent upon the presence, absence or amount of analyte, which gas creates one or more bubbles in the liquid sample which act to alter the flow of liquid along a flow path; and determining an alteration of flow in the liquid wherein the alteration of flow of liquid along the flow path is indicative of the presence and/or amount of analyte in the liquid sample.

Assay device comprising bubble-forming means

Disclosed is a fluidic assay device for assaying at least one property of a liquid sample, the device comprising: The invention relates to a fluidic device for the passage of a liquid. It also relates to an assay device suitable for measurement of the amount and/or presence of an analyte in, or property of, a fluid sample.

Fluidic indicator device

Disclosed is a fluidic assay device for assaying at least one property of a liquid sample comprising: a liquid sample application region; at least one test flow path in liquid flow communication with the sample application region; a reference flow path in liquid flow communication with the sample application region; and a junction region, at which the test flow path and the reference flow path contact one another, the junction region typically comprising an outlet, conduit, chamber or other portion which permits the onward flow of liquid; wherein a liquid flowing along the reference flow path, upon reaching the junction region, has the effect of preventing the flow of liquid along the test flow path. The invention relates to a fluidic device for the passage of a liquid and an assay device suitable for measurement of the amount and/or presence of an analyte in, or property of, a fluid sample.
