Abstract:
1. A positioning method for biochip spotting, comprising, the following steps: (a) providing reference points and spotting positions on a biochip substrate; (b) taking an image of the position of each reference point and an image of the position of each spotting position to calibrate the position of the biochip substrate; (c) calculating a first spotting position and performing spotting according to position information of the images of the positions of reference points of step (b); (d) taking and recording the image of the spotted position; (e) calculating to make feedback correction for reducing error of size and spotted position and set up a next spotting position according to position information of the image of step (d) and then performing spotting; and (f) repeating step (d) to step (e) until all spotting is completed on the biochip substrate.
