The adsorption behavior of 1,4-benzenedithiol (1,4-BDT) on colloidal gold and silver surfaces has been investigated by means of surface-enhanced Raman scattering (SERS). 1,4-BDT chemisorbed dissociatively on both gold and silver surfaces but as mono-and dithiolate, respectively. Regardless of the bu

Monolayers of glutathione (GSH) and 3-mercapto-1,2-propanediol (MG) on gold were tested for their bioreactivity by assessing the degree of inflammatory reaction as manifested by the adherence and activation of platelets and white blood cells (wbc) after exposure to blood ex vivo. Surface composition
The adsorption of pentan-l-01 on thin gold film electrodes was studied by capacitance and surface conductance, The pentan-l-01 adsorption conforms to the Frumkin isotherm. The free energy of adsorption at the potential of maximum adsorption shows that the adsorption of pentan-l-01 is weaker on gold
Au and Ag clusters of 3-nm mean diameter were prepared with 1,4-benzenedimethanethiol (BDMT) as the capping molecule. In both the monolayer-capped clusters, BDMT adsorbs in the dithiolate form in contrast to in the 2D monolayers, where the dithiolate form exists only in the case of Ag. As a result,
