MICROARRAY FABRICATION TECHNIQUES AND APPARATUS

摘要

Disclosed is a microarray printing system (100) and methods of printing probe microarrays (1101). The system has a print head (101, 200, 805, 1003, 1700, 1800, 1900) formed of one or more bundles (201-221, 604) of individual capillaries, (102, 301, 402a, 402b, 502a, 502b, 603a, 603b, 802) such as light-guiding capillaries. The bundles may especially be random bundles of capillaries that provide a large number of probes (807, 1006a, 1006b, 1206) on the surface of a substrate. Methods of registering or correlating the distal and proximal ends of the capillaries are also provided. Further, the invention provides methods and equipment for identif
