A propyltrimethoxysilane-modified 2,2'-bipyridine ligand is synthesized and its acetonitrile solutions are used to prepare monolayers of the molecule on glass surfaces. Absorption and X-ray photoelectron spectroscopy demonstrate that the modified glass surfaces bind Cu2+ with a 1 : 1 ratio with respect to the 2,2'-bipyridine moieties under the chosen preparative conditions, producing materials bearing 0.016 mu g cm(-2) of copper. Although in trace amounts, the bound Cu2+ cations exert a significant microbicidal effect against Escherichia coli and Staphylococcus aureus

Abstract
A propyltrimethoxysilane-modified 2,2'-bipyridine ligand is synthesized and its acetonitrile solutions are used to prepare monolayers of the molecule on glass surfaces. Absorption and X-ray photoelectron spectroscopy demonstrate that the modified glass surfaces bind Cu2+ with a 1 : 1 ratio with respect to the 2,2'-bipyridine moieties under the chosen preparative conditions, producing materials bearing 0.016 mu g cm(-2) of copper. Although in trace amounts, the bound Cu2+ cations exert a significant microbicidal effect against Escherichia coli and Staphylococcus aureusFile in questo prodotto:
