CA 2296698

The invention relates to a method suitable for mass production and a device for fixing micro- and/or nano-objects. The invention is characterized in that several liquid phases containing solid micro- and/or nano-objects (2) are filled into the wide filling holes (8) of conically narrowing tubes (4) and transported in the direction of a narrow outlet opening (7) of said tubes (4); the shape and size of the narrow outlet openings (7) prevent the passage of more than one object (2); the narrow outlet openings (7) of the tubes (4) are positioned three-dimensionally (in directions x, y and z) in relation to a support plane (11) before the objects (2) emerge; and the micro- and/or nano-objects (2) having passed through the outlet opening (7) are physically and/or chemically and/or mechanically fixed on the support (1) in the defined position.

L'invention concerne un procédé adapté pour la production de masse et un dispositif pour fixer des micro-objets et/ou des nano-objets. L'invention se caractérise en ce que: plusieurs phases liquides contenant des micro-objets et/ou nano-objets (2) solides sont introduites chacune dans une ouverture de remplissage (8) d'un tube (4) se rétrécissant de façon conique et acheminées vers un orifice de sortie (7) étroit du tube (4), les orifices de sortie (7) étroits empêchant, de part leur forme et leur taille, le passage de plus d'un objet (2); les orifices de sortie (7) étroits des tubes (4) sont positionnés de façon tridimensionnelle (dans les sens x, y et z), par rapport à un plan de support (11), avant la sortie des objets (2), et les micro-objets et/ou nano-objets (2) sont, après leur sortie par l'orifice de sortie (7), fixés dans la position prescrite, physiquement et/ou chimiquement et/ou mécaniquement, sur le support (1).
