APPARATUS AND METHOD FOR DISPENSING PARTICLES IN FREE-FLYING DROPS ALIGNED USING AN ACOUSTIC FIELD

摘要

An apparatus for dispensing particles in free-flying liquid drops includes afluid chamberfluidically coupled to a nozzle, a sound source configured to generate, in thefluidchamber, an acoustic field by which particles in a liquid in the fluid chambermay bealigned in an arrangement, and a drop-on-demand mechanism configured to, at aselected point in time, selectively dispense from the nozzle an individualliquid dropcontaining one or several particles.
