Abstract: A device and a method of using the device for improving sensitivity, speed, and easy-to-use of a colorimetric assay of a liquid sample are provided. The device includes a first plate and a second plate, spacers, and a textured surface. The two plates each have a sample contact surface and are movable relative to each other into an open configuration or a closed configuration. The sample is deposited on one or both plates in the open configuration. Thereafter, the closed configuration is formed where the plates compress at least part of the deposited sample into a continuous layer. The textured surface is disposed on the sample contact surface of the second plate and has a textured structure that scatters light, from which an optical signal such as a colorimetric or fluorescent signal can be obtained for analyzing the sample.

Abstract: The disclosure provides a spacing-changeable device and a method using both lateral flow and compressed open flow for assaying a liquid sample. The device includes a first plate, a second plate, and an exterior liquid sample contact area. The spacing between the two plates are changeable to form different configurations including a first and second configurations. In the first configuration, the two plates face each other and form at least two gaps including a spacing-1 and a spacing-1?. The spacing height of the spacing-1? has a size that allows a liquid sample to flow into the spacing-1?. In the second configuration, the two plates are pressed, which changes spacing-1 and spacing-1? to spacing-2 and spacing-2?, respectively, and the spacing-2? has a spacing height larger than that of spacing-2. In the second configuration, the sample flows and spreads in areas of spacing-2 and spacing-2?.

Abstract: Among other things, the present disclosure is related to devices and methods of performing biological and chemical assays, such as but not limited to immunoassays and nucleic assay acid, particularly a homogeneous assay that does not use a wash step and that is fast (e.g., 60 seconds from dropping a sample to displaying results). The present disclosure is related to both competitive and non-competitive homogeneous assays.
