Abstract

The present disclosure provides a method for patterning a nanoparticle layer, including steps of: (S1) connecting a first base to a surface of a predetermined area of a substrate, to form a substrate modified with the first base in the predetermined area of the substrate; (S2) depositing the nanoparticle in the predetermined area of the substrate, to form a nanoparticle layer in the predetermined area of the substrate by self-assembling, a ligand of the nanoparticle includes a second base, and the first base and the second base being connected by a hydrogen bond; and (S3) removing the nanoparticle in a non-predetermined area of the substrate.
