      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.},
