Gold nanoparticles, 20-30 {Angstrom} in diameter, completely covered with alkylthiol chains, have been characterized using NMR, FT-IR, transmission electron microscopy, and differential scanning calorimetry. A chainlength dependent phase transition related to a melting process is observed for C{sub 12-} to C{sub 20}-derivatized gold particles. These studies indicate that a close relationship exists between self-assembled monolayers formed at planar surfaces and at the highly curved surfaces of these spherical nanoparticles.
