abstract = {For a comparative cytotoxicity study, nanoparticles of the
noble metals Rh, Pd, Ag, Pt, and Au (spherical, average
diameter 4 to 8 nm) were prepared by reduction in water and
colloidally stabilized with poly(N-vinyl pyrrolidone) (PVP).
Thus, their shape, size, and surface functionalization were
all the same. Size and morphology of the nanoparticles were
determined by dynamic light scattering (DLS), analytical
disc centrifugation (differential centrifugal sedimentation,
DCS), and high-resolution transmission electron microscopy
(HRTEM). Cell-biological experiments were performed to
determine the effect of particle exposure on the viability
of human mesenchymal stem cells (hMSCs). Except for silver,
no adverse effect of any of the metal nanoparticles was
observed for concentrations up to 50 ppm (50 mg L−1)
incubated for 24 h, indicating that noble metal
nanoparticles (rhodium, palladium, platinum, gold) that do
not release ions are not cytotoxic under these conditions.},
