Abstract

Systems, methods, and devices are provided for manipulating objects in a liquid using a pulsed acoustic field that is modulated in amplitude. The amplitude modulated pulsed acoustic field may form the objects into a layer or layers. The objects may be colloidal objects having an average size of about 50 nm to about 5 μm, or a mixture of colloidal and non-colloidal objects.
