Controlling gold nanoparticle assembly on electron beam-reduced nitrophenyl self-assembled monolayers via electron dose

- Citrate-passivated gold nanoparticles deposited on self-assembled monolayers.
- Self-assembled monolayers patterned chemically using electron beam lithography.
- Conversion of nitro (NO2) moieties to amino (NH2) moieties.
- Specific adsorption of nanoparticles to patterned amino regions.
- Overexposure reduced feature quality and regional selectivity of adsorption.
