Fe and Cu nanoparticles have been used in nanomedicine as possible therapies
against cancer, vehicle for drugs and genetic material, thermal therapy, as
bactericides, fungicides and antivirals, however there are few work that study
the properties of bimetallic nanoparticles. In the present work we propose to
standardize a green synthesis method for the 3 nanomaterials which will be
evaluated on cytotoxic studies in cell lines. Particles were characterized by Uvvis,
where it was found that the maximum absorption peak
corresponding to surface plasmon resonance of nanoparticles are 375 nm for
FeNPs, 467nm for CuNPs and 390 nm for core@shell Fe@CuNPs. Samples were
analyzed by TEM, sizes of 7.3 ± 2.1 nm were observed for Fe, 4.1 ± 2.4nm for Cu
and 7.8 ± 2.8nm for Fe@Cu. Element mapping by EDS for Fe@CuNPs showed
that both metals overlap, where Cu material is localized discreetly over FeNPs.
X-ray diffraction experiments showed that FeNPs correspond to magnetite and
CuNPs to cuprite. On bimetallic Fe/Cu nanoparticles,
EDS analysis showed that atomics proportions are 90:10. The cytotoxic effect of
the iron nanomaterial was evaluated on HUVEC cells by MTT assay, where it was
found that FeNPs did not produce cell death.
