THE BRUST–SCHIFFRIN METHOD: TWO-PHASE SYNTHESIS AND
STABILIZATION BY THIOLS:
Another procedure that has become extremely popular for smaller AuNPs synthesis
in organic solvent is two phase reduction method developed by Brust et. al. This syn-
thesis technique is inspired by Faraday’s two-phase system and uses thiol ligands that
strongly bind gold due to the soft character of both Au and S [11]. The stabilization
of AuNPs with alkanethiols was first reported in 1993 by Mulvaney and Giersig, who
showed the possibility of using thiols of different chain lengths for stabilization [50].
The method has had a considerable impact on the overall field in less than a decade.
