title: Effect of polar organic vapors on surface potential of Au nanoparticle aggregates probed by surface-enhanced Raman scattering of 2,6-dimethylphenylisocyanide.
abstract: We demonstrate by means of surface-enhanced Raman scattering of 2,6-dimethylphenylisocyanide that the surface potential of Au nanoparticle aggregates changes upon contact with polar organic vapors such as acetone and ammonia by as much as +0.16 and -0.56 V, respectively.
