Beschreibung
Zusammenfassung:	The present invention relates to the field of biochips, and provides a chip surface linker and a preparation method and a use therefor. The chip surface linker is obtained by means of applying a direct current voltage to an aromatic amine bonding molecule in the presence of an acid and a nitrite to cause a reaction with a chip surface to form a bonding molecular group connected the chip surface, and then using a functional molecular for reaction and modification to add a functional molecular group containing a hydroxyl group and an ester group. The chip surface linker obtained in the present invention is able to bond more stably with a chip surface, being stable in hot water and basic conditions, and features relatively good electrical conductivity, stability during energization, and resistance to organic solvents required for nucleic acid synthesis, and is thus very advantageous for subsequent nucleic acid synthesis and other uses.
