Deposition of particles at desired locations using plasmonic enhancement

A method of particle deposition, the method comprising:

• providing a plasmonically active material comprising a region comprising a plasmonically enhanced electric field and a region without a plasmonically enhanced electric field, the plasmonically active material comprising gold;
• simultaneously introducing a light beam and applying a precursor molecule to the plasmonically active material causing particle deposition on the plasmonically active material comprising the region comprising the plasmonically enhanced electric field, the light beam comprising photons having wavelengths from 250-2000 nm;
• and
• directing particle deposition in selected locations of the plasmonically active material comprising the region comprising the plasmonically enhanced electric field;
• whereby the region of the plasmonically active material without the plasmonically enhanced electric field does not exhibit particle deposition.
