Journal of Colloid and Interface Science

We show that nanoparticle monolayers self-regulate their 2D organization to reach a common electrostatic steady state, characterized by a constant interfacial surface potential (ΔV ≈ 150 mV) and a fixed single-particle repulsive energy (U ≈ 2 × 10<sup>-23</sup> J), independently of ionic strength and ion identity. Variations in electrolyte composition instead control the nanoparticle surface exce…
