the most ubiquitous synthesized AuNP sizes (29 kDa, ∼2 nm)
and its mass-spectrometrical analysis (Au144(SR)60),43−46 and
the AuNP structure incorporates the structural details observed
for several cluster sizes, where the Au core is a nearly spherical
polyhedron and a part of the Au atoms participate (in oxidized
form) in the Au−SR ligand shell.3
