Document Type and Number:
WIPO Patent Application WO/2024/084031
Kind Code:
A1
Abstract:
The present invention relates to a method and equipment for transferring an object from a donor substrate (30) towards a target substrate (40), the donor substrate (30) containing the objects that are to be transferred and have dimensions (Dx, Dy, Dz), the transfer being ensured by local energy excitation of the liquid to form a local cavitation bubble at an object, characterized in that: a. the substrate consists of a micro-well plate having a plurality of wells each forming a receptacle having an open upper base that tapers towards the bottom, the width (L) of the base of the wells being L > 2DxDy and the height (h) of the well being h > 2Dz; and b. the transfer takes place - at a first energy level E1 if the ratio of the dimension (Dz) of the object to the thickness (e) of the liquid film is less than 1, - at a second energy level E2 > E1 if the ratio of the dimension (Dz) of the object to the thickness (e) of the liquid film is greater than 1.
