DEVICE AND METHOD FOR ADMINISTERING PARTICLES, ALIGNED WITH THE USE OF AN ACOUSTIC FIELD, IN FREE-FALLING DROPS

摘要

A device for administering particles (10) in free-falling liquid drops (12) has a fluid chamber (14), which is coupled fluidically to a nozzle (16), a sound transducer (18) which is configured to generate an acoustic field in the fluid chamber (14), by means of which particles (10) in a liquid in the fluid chamber (14) can be aligned in an arrangement, and a drop-on-demand mechanism, which is configured to administer a single liquid drop, which contains one or more particles, from the nozzle at a selected instant in a targeted manner.
