Claim:
1. An automatic sample loading device for microarray chip, characterized in that the automatic sample loading device comprises at least one sample loading unit, said sample loading unit is formed by sealing a cover layer with a hydrophilic surface to a microfluid layer, the cover layer is configured with at least two through holes, and the microfluid layer is configured with a hollow hybridization chamber and at least two hollow microfluid channels, wherein one end of each of the microfluid channels is connected to the hybridization chamber, and the other end is connected to one of the through holes of the cover layer, wherein the contact angle between the surface of the cover layer which contacts the microfluid layer and a sample solution is less than 90 degrees when the sample solution is water, and wherein the contact angle between the other surface of the cover layer and a sample solution is in the range of 90 to 180 degree when the sample solution is water.
