Electron transport through nanoparticle assemblies is a fundamental process to control their physical properties that are determined by coupling and arrangement of individual nanoparticles (NPs), depending on size, shape, and composition. In order to understand the charge transport in one‐dimensional arrays of NPs, Govor et al. recently have studied how it takes place through a single NP covered with stabilizer molecules. For this purpose, they prepared a metal–NP–metal configuration where a citrate capped gold particle was located between two Au electrodes. In their Letter on pp. 16–18 , Govor et al. now examine the charge transport between two Au electrodes bridged by a one‐dimensional chain of NPs (7–10 particles per chain) and show that similar (compared to the one‐particle device) conductance fluctuations at constant bias voltage occur. Moreover, they found that the NPs inside the chain are dislocated under the influence of the electric field applied between the Au electrodes. The latter effect gives rise to fluctuations of the differential conductance depending on the bias voltage.
