Abstract
Disclosed are methods and devices for interfacing to or interacting with the flow of liquid passing into or through lateral-flow assays and related paper- or membrane-based in-vitro diagnostic testing platforms. This is done for the purpose of improving their performance, sensitivity, accuracy, repeatability, degree of multiplexing, and/or level of quantitation, and/or reducing their inherent limitations while maintaining, in large part, their simplicity, cost effectiveness, and ease of use. New methods are disclosed for pre-sample purification, aliquoting, sequential liquid delivery, flow control and other functions that are largely automatic and require no action on the part of the user.
