Abstract

Device for locating biological cells of at least one size, including a fluid cavity (3), fluid connection means (6.1, 6.2) configured to allow the introduction of liquid and cells into the fluid cavity, a plate (4) provided with an accommodating surface (8) having properties of adhesion vis-à-vis cells, said plate (4) being suspended in the fluid cavity (3), means (10) for vibrating the plate (4) in at least one stationary mode including at least one actuator (16) intended to act on the plate (4) and a control unit (UC) configured to control the at least one actuator so as to actuate the vibrating plate in a stationary mode at a wavelength greater than the size of the cells.
