“…SAMs that are based on thiol-gold chemistry have been widely employed in the fields of chemistry, physics, molecular biology, pharmaceutical engineering and materials science [1][2][3] . Considerable interests in such systems have increased, owing to their versatile applications, including the fabrication of nanopatterning 4,5 , molecular-scale devices 6,7 , optical materials 8,9 , formulation of biosurfaces 10 and support for cell culture 2,11 . The strength of the gold-sulphur (Au-S) interaction formed between thiols and gold surfaces provides the basis to fabricate robust SAMs for diverse applications.…”
