1. A method for transferring one or more nanostructures from a first substrate to a second substrate, the method comprising:
applying a coating of a crosslinkable copolymer over one or more nanostructures on a surface of the first substrate, wherein the crosslinkable copolymer is polymerized from one or more non-crosslinking monomers and one or more comonomers bearing crosslinkable groups;
heating the crosslinkable copolymer to induce crosslinking of the crosslinkable copolymer and to form bonds between the crosslinkable copolymer and the surface of the first substrate;
releasing the one or more nanostructures and the crosslinked copolymer from the first substrate;
transferring the one or more nanostructures and the crosslinked copolymer onto a surface of the second substrate; and
removing the crosslinked copolymer from the one or more nanostructures.
