Abstract
An apparatus for transferring bio-ink onto a target having a slide defining a receiving area of a film of fluid containing inhomogeneities, a laser source associated with controlled diversion means and an optical block for focusing in a plane of the fluid film in order to apply a local pulse, wherein the apparatus also comprises imaging means and means for analyzing images in order to recognize the geometric positions of the inhomogeneities in the film, and an observable feature of each of the inhomogeneities (size, shape factor, type of particles, age of the particle, density, type of biomaterial, molecule, etc.) recognized by the appropriate analysis means. The apparatus further comprises selection means for selecting at least one of the inhomogeneous areas, and means for controlling the diversion in order to direct the laser beam toward the position of the inhomogeneous area and trigger the firing of the laser.
