Method of forming a multilayer aggregate of objects
A method of forming a multilayer aggregate (120) of objects (O) in a channel (2) comprising a liquid (L), said method comprising: a) providing objects (O) at first (50) and second (60) superposed regions of the channel (2), b) obtaining first (110) and second (111) aggregates of objects (O), optiona...

Zusammenfassung: | A method of forming a multilayer aggregate (120) of objects (O) in a channel (2) comprising a liquid (L), said method comprising:
a) providing objects (O) at first (50) and second (60) superposed regions of the channel (2),
b) obtaining first (110) and second (111) aggregates of objects (O), optionally by applying transverse acoustic waves, preferably stationary waves, within each region to objects (O), and
c) bringing said first (110) and second (111) aggregates into contact to form said multilayer aggregate (120) of objects (O) by submitting said first (110) and second (111) aggregates to:
o gravity in absence of acoustic waves, or to
o acoustic waves, optionally stationary waves, inducing displacement of said first (110) and second (111) aggregates toward each other. |
