摘要
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.
