US Patent 7829351 - Transfer coating of nanostructures


This patent from Nanosys has some relatively early priority (9/25/2003) and includes some basic claims to transferring films of nanofibers or semiconductor nanowires to a substrate. Claim 1 reads:

1. A method, comprising:

forming a plurality of nanostructures on a transfer substrate;

providing a receiving substrate which comprises one or more selected regions of an adherent material;

mating the transfer substrate with the receiving substrate wherein the nanostructures adhere to the one or more selected regions during the mating step; and

separating the transfer substrate from the receiving substrate to leave a population of nanostructures adhered to the receiving substrate.
