A surface functionalizing method for use in high-throughput in situ synthesis of nucleic acids by 3D inkjet printing. The method includes subjecting a surface of a substrate to hydroxyl enrichment treatment; adding hydrophobic molecules to the surface of the substrate, the hydrophobic molecules being not reactive with phosphoramidite monomers; spraying, by a multi-channel piezoelectric inkjet head assembly, an etching ink to a predetermined area on the surface of the substrate for micro-etching, the etching ink being prepared with a fluoride compound reactive with the hydrophobic molecules; and adding hydrophilic molecules to the surface of the substrate. By using the method, a functionalized surface with given areas being patterned can be formed on the surface of the substrate, and then a same multi-channel piezoelectric inkjet head assembly can be directly used for subsequent high-resolution printing of phosphoramidite monomers and synthesis of nucleic acids.
