Abstract

The assay devices, assay systems and device compo-nents of this invention comprise at least two opposing sur-faces disposed a capillary distance apart, at least one of which is capable of immobilizing at least one target ligand or a conjugate in an amount related to the presence or amount of target ligand in the sample from a fluid sample in a zone for controlled fluid movement to, through or away the zone The inventive device components may be incorporated into conventional assay devices with mem-branes or may be used in the inventive membrane-less de-vices herein described and claimed. These components in-clude flow control elements, measurement elements, time gates, elements for the elimination of pipetting steps, and generally, elements for the controlled flow, timing, deliv-ery, incubation, separation, washing and other steps of the assay process.
