Abstract:
1. An assay device comprising: a reaction chamber located in a microchannel; at least two sets of individually encoded functionalized microcarriers; at least one side of the microchannel being configured to allow for optical observation or identification of said microcarriers in the microchannel; each said microcarrier of one of the at least two sets having identical functionalization; a cross-section of the reaction chamber having a height and a width that is greater than the height; a cross-sectional width of each said microcarrier being less than half of the width of the cross-section of the reaction chamber such that at least two microcarriers arranged side by side without touching each other can pass each other in a longitudinal direction when they move at different speeds within the microchannel; and a movement restricting device structured and arranged to limit movement of the microcarriers.
