METHOD AND DEVICE FOR THE CONTACTLESS LASER-ASSISTED MICROINJECTION, SORTING AND PRODUCTION OF BIOLOGICAL OBJECTS GENERATED IN A PLANAR MANNER

摘要

The invention concerns a method and device for the contactless microinjection, sorting and production of biological objects. According to the invention, on a planar carrier (2) an object field or the object itself, located on the carrier (2), is cut out with a laser beam (6) and transferred by means of a laser-induced transport process to a collector substrate (5) which is disposed directly above or below the carrier. During the cutting-out process, either the laser beam (6) moves in a closed curve about the object or the object itself is cut directly out of the carrier (2) in a computerized manner. This method enables individually selected objects to be spatially separated and sorted from a very large number of objects. The method can also be used to separate specific cells from tissue sections. The method is further suitable for microinjecting given substances into individual biological objects, such as for example cells, and then sorting the latter.
