Single-electron transfer across an alkanethiolate-protected Au nanoparticle monolayer is observed (see figure) through deliberate control of the nanoparticle structure, interparticle interactions, and temperature. The system is analogous to the Coulomb-staircase phenomenon seen in STM-based measurements of individual particles.
