Abstract
A method of forming a multilayer aggregate of objects in a channel including a liquid, the method including: a) providing objects at first and second superposed regions of the channel, b) obtaining first and second aggregates of objects, optionally by applying transverse acoustic waves, preferably stationary waves, within each region to objects, and c) bringing the first and second aggregates into contact to form the multilayer aggregate of objects by submitting the first and second aggregates to: gravity in absence of acoustic waves, or to acoustic waves, optionally stationary waves, inducing displacement of the first and second aggregates toward each other.
