1. A device for locating biological objects on an accommodating surface, the device comprising:
a fluid cavity within a housing;
at least one fluid connector configured to introduce liquid and biological objects into the fluid cavity;
a plate provided with said accommodating surface having properties of adhesion vis-à-vis biological objects, said plate being suspended in the fluid cavity;
at least one actuator for vibrating the plate in at least one stationary mode, said at least one actuator being configured to act on the plate; and
a control unit configured to control the at least one actuator so that the plate vibrates in a stationary mode with a wavelength λ of between 3 times and 20 times a size of the biological objects,
wherein a bottom surface of the plate is supported by a support structure, the support structure includes a plurality of columns and the plate is supported on free ends of the plurality of columns.
