Method for manipulating a fluid medium within a flow cell using acoustic focusing

摘要

A system and method for analyzing one or more particles in a flow cell comprises focusing the one or more particles in a fluid stream with an acoustic standing wave to acoustically focus the one or more particles in a flow cell. The fluid is transited within the flow cell with a linear flow velocity ranging between about 0 meters/second and about 10 meters/second in the forward or reverse direction.
