Ion permeability of SAMS on nanoparticle surfaces

The ion permeability of self-assembled monolayers (SAMS) formed on the surface of charged alkanethiol-protected gold nanoparticles, so-called monolayer-protected clusters (MPCs), is reported. It is shown that mo o-MPCS in spite of their large size and different nature of the electron transfer process can be treated to redox molecules analogously.
