Abstract
A method is provided for manipulating objects in a cavity including a liquid, the method including providing in at least one region of the cavity objects capable of absorbing light in a given wavelength range, forming an aggregate of the objects by submitting them to an acoustic field, and disrupting the aggregate by submitting the aggregate to a light beam emitting at the given wavelength range. Also provided is a device for manipulating objects.
Claims15
A method for manipulating objects in a cavity comprising a liquid, said method comprising:
- a) providing objects in at least one region of the cavity;
- b) forming an aggregate of the objects within a levitation plane by submitting them to an acoustic field;
- and
- the objects are light absorbing objects in a given wavelength range, and said method further comprising the step of:
- c) disrupting the aggregate within the levitation plane by submitting said aggregate to a light beam emitting at the said given wavelength range, the objects migrating along the levitation plane and being gradually expulsed from the aggregate itself.
A method for separating objects in a cavity comprising a liquid, said method comprising:
- a) providing in at least one region of the cavity objects comprising a first plurality of objects capable of absorbing light in a first wavelength range and a second plurality of objects not capable of absorbing light in the first wavelength range;
- b) forming an aggregate within a levitation plane of the first plurality of objects and the second plurality of objects by submitting them to an acoustic field;
- and
- c) expulsing within the levitation plane the first plurality of objects from the aggregate by submitting the aggregate comprising first plurality of objects and second plurality of objects to a light beam emitting at the said first wavelength range, the first plurality of objects migrating along the levitation plane and being gradually expulsed from the aggregate itself.
