Use of a compound, microarray chip substrate, microarray chip and use and method thereof. The present application provides use of a compound, or a geometric isomer, tautomer, isotopically labeled, hydrate, solvate or salt thereof in chip surface modification. Also provided is a microarray chip substrate modified by the compound, and a microarray chip comprising the microarray chip substrate. The microarray chip substrate of the present application can greatly improve the surface modification function by surface modification, improve nucleic acid synthesis yield, amplify detection signal, and avoid non-specificity and cross-talk. It has a wide application prospect.

The use of a compound, a microarray chip substrate, and a microarray chip and the use thereof and a method therefor. The present application provides a compound, or a geometric isomer, a tautomer, an isotope-labeled compound, a hydrate, a solvate or a salt thereof in the surface modification of a chip. Further provided is a microarray chip substrate modified by the compound, and a microarray chip comprising the microarray chip substrate.

The application belongs to the technical field of biology, and discloses a microarray chip, a preparation method and application thereof. The microarray chip has hydrophilic reaction holes and hydrophobic non-reaction areas, the depth of the reaction holes is 20-50 mu m, the etching depth is much higher than the depth of 3-10 mu m of traditional laser etching, the hydrophobic angle of the non-reaction areas is more than 110 degrees, and the chip surface is flat and smooth. The application adopts double photolithography and surface hydrophobization treatment, and can quickly prepare the microarray chip with multiple hydrophilic reaction holes and hydrophobic non-reaction areas, which meets the needs of large-scale industrial production; different patterned masks can be designed to obtain reaction holes with different shapes for different detection scenes.
