    摘要: A microfluidic device for isolation objects from a liquid suspension comprises at least one fluid inlet and at least one fluid outlet, at least one fluid channel fluidically connecting the at least one fluid inlet to the at least one fluid outlet, a plurality of passive hydrodynamic trapping sites arranged along the at least one fluid channel, each trapping site configured to trap a defined number of objects from a liquid suspension flowing along the at least one fluid channel, and a plurality of nozzle channels, wherein each nozzle channel is in fluidic communication with one of the trapping sites and fluidically connects this trapping site with an associated nozzle orifice. A force may be applied concurrently to the trapped objects and the liquid columns in the nozzle channels so that a liquid aliquot containing the defined number of objects is ejected from each nozzle orifice.
