abstract = {Ultrasmall gold nanoparticles (diameter about 2 nm) were
surface-functionalized with cysteine-carrying precision
macromolecules. These consisted of sequence-defined
oligo(amidoamine)s (OAAs) with either two or six cysteine
molecules for binding to the gold surface and either with or
without a PEG chain (3400 Da). They were characterized by
1H NMR spectroscopy, 1H NMR diffusion-ordered
spectroscopy (DOSY), small-angle X-ray scattering (SAXS),
and high-resolution transmission electron microscopy. The
number of precision macromolecules per nanoparticle was
determined after fluorescent labeling by UV spectroscopy and
also by quantitative 1H NMR spectroscopy. Each
nanoparticle carried between 40 and 100 OAA ligands,
depending on the number of cysteine units per OAA. The
footprint of each ligand was about 0.074 nm2 per cysteine
molecule. OAAs are well suited to stabilize ultrasmall gold
nanoparticles by selective surface conjugation and can be
used to selectively cover their surface. The presence of the
PEG chain considerably increased the hydrodynamic diameter
of both dissolved macromolecules and
macromolecule-conjugated gold nanoparticles.},
