In this report, magnetic resonance imaging (MRI), and
cell labeling (CL) contrast agent of single-phase mixed
DyEuO
3
and
HoEuO
3
nanoparticles
has been synthesized. They were characterized with XRD,
FT-IR, TGA, PL, HRTEM, SQUID magnetometer and MRI
instrument. There is no appreciable cytotoxicity up to
500 M concentration. The synthesized nanoparticles
were monodisperse with average diameter (d
avg
)
of 2 nm. Both samples were found to be paramagnetic and
emitted strong red fluorescence. From in vivo MRI
experiment we found that the negative contrast had been
enhancement on mouse liver and kidneys after the
injection of nanocolloid.
