Gene chip tester

Abstract

A gene chip tester is composed of fluorescent exciting unit, probing unit, scan unit, A / D converter and computer for processing the signals from probing unit and A / D converter, and controlling scan unit to move in X and Y directions.

Description

technical field [0001] The invention relates to a detector, in particular to a gene chip detector. Background technique [0002] As far as the applicant knows, the latest gene chip scanner is the Model 418 laser gene chip scanner produced by the American AFFYMETRIX company. The problems existing in this scanner are: 1. It cannot be used for visual observation and inspection of the gene chip; 2. The scanning of the gene chip is realized by moving the lens, which is easy to damage the microscope objective lens and affect the accuracy of the optical system; 3. Using a photomultiplier tube as the detector of the confocal optical path leads to a complicated optical path and high cost. Contents of the invention [0003] The primary technical problem to be solved by the present invention is to realize the fast scanning of the gene chip under the condition that the optical system remains still during scanning. The quality monit...
