Using conduction electron spin resonance (CESR) we demonstrate that the electronic properties of gold nanoparticles respond to changes in the chemical identity of thiolates bound to the surface of the particles.  In particular, we demonstrate that both aromatic and aliphatic ligands can be used to control the Fermi Level of the metallic core of the particles. This is true, even for very subtle changes in ligand, such as the elongation of straightchain alkanethiolates.
