Abstract
Official abstract text for this publication.
A multi-layered device for detecting the presence or absence of an analyte within a test sample is described. The device includes a sensing layer and a control layer. The sensing layer is configured to support a reaction so as to exhibit a signal indicative of the presence or absence of the analyte in the test sample. The control layer is in fluid communication with and vertically adjacent to the sensing layer and includes a reagent capable of inhibiting the reaction and/or other unwanted side reactions at the sensing layer after a certain period of time by diffusive movement of the reagent from the control layer to the sensing layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-layered device for detecting the presence or absence of an analyte within a test sample, the device comprising: a sensing layer, the sensing layer configured to support a reaction so as to exhibit a signal indicative of the presence or absence of the analyte in the test sample wherein the sensing layer is covered by a material defining an opening, the opening permitting the test sample to contact the sensing layer; and a control layer, the control…
