Beschreibung
Zusammenfassung:	The present invention relates to a method for performing a chemical and/or a biological assay comprising the following successive steps of: a) providing an assay device (19) with a microchannel (20) having an inlet (28) and an outlet (30) and further comprising restricting means (34) designed to restrict the movement toward the outlet (30) of microparticles (10) introduced in the microchannel while(20) letting a fluid to flow through the restricting means (34), b) introducing microparticles (10) in the microchannel (20) via the inlet (28), c) restricting the movement of said microparticles (10) in the microchannel (20) toward the outlet using restricting means (34), d) flowing a fluid sample through the microchannel (20), e) performing a biological and/or chemical read-out on each microparticle (10), the method further comprising the steps of: f) moving the microparticles (101, 102, 103, 104) in the microchannel, and g) repeating successively the steps d) and e).
