Abstract
Disclosed are methods and systems for transferring dry or semi-dry nanoparticles onto a substrate. In one embodiment, this includes the steps of providing a roller comprising an elastomeric stamp; transferring nanoparticles in a dry or 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. The substrate, in other embodiments, can have a relief structure.

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.
A method of patterning a substrate comprising:
- forming a film of nanoparticles on a substrate surface, wherein the nanoparticles are in a dry state or a semi-dry state;
- providing a roller comprising an elastomeric stamp having a relief structure, the relief structure capable of forming a first pattern;
- and
- removing a portion of the nanoparticles from the substrate surface by rolling the elastomeric stamp onto the substrate surface, whereby remaining nanoparticles on the substrate surface form a negative of the first pattern.
A system for transferring dry or semi-dry nanoparticles onto a substrate comprising:
- a roller comprising an elastomeric stamp;
- nanoparticles;
- a donor substrate for transferring the nanoparticles in a dry state or a semi-dry state, and which contact the surface of the donor substrate, from the donor substrate onto the elastomeric stamp;
- and
- a receiver substrate for receiving the dry or semi-dry nanoparticles from the elastomeric stamp onto the receiver substrate during rolling the elastomeric stamp onto the receiver substrate.
