Abstract
A substrate structured to define thereon a fluid flow channel and/or a fluid control feature is described. The substrate may additionally comprise a capture zone and/or a test zone, for use as a test strip for determining presence or absence of an analyte of interest, such as an infectious agent or a biomarker. Reagents are deposited in the capture zone and/or test zone as an array of drops.
