Primary human osteoblasts were cultured on self-assembled monolayers (SAMs) of alkylthiols on gold with carboxylic acid and methyl termini, and the kinetics of cell attachment and proliferation were measured. Over 90 min approximately twice as many cells attached to carboxylic-acid-terminated monola
## Abstract 1βDodecanethiol assembly on polycrystalline gold electrodes at fixed positive potentials has been investigated by chronoamperometry and electrochemical quartz crystal microbalance and the films formed characterized by cyclic voltammetry and electrochemical impedance spectroscopy. It was
Long-chain alkanethiols I R(CH,),SH] and substituted phenylthioureas (RPhNHCSNH,) adsorb from solutions on the surface of gold. Analysis by XPS indicates that the binding energies of the S 2p and Au 4d, peaks in alkanethiol monolayers are 162.3 and 335.4 eV, which are 1.4 and 0.4 eV higher than thos
