1. A method of transferring dry or semi-dry nanoparticles onto a substrate comprising the steps of:
providing a roller comprising an elastomeric stamp;
transferring nanoparticles in a dry state or a semi-dry state, and which contact the surface of a donor substrate, from the donor substrate onto the elastomeric stamp; and
depositing the dry or semi-dry nanoparticles from the elastomeric stamp onto a receiver substrate by rolling the elastomeric stamp onto the receiver substrate.
