was investigated, and it was unveiled that F@BSA@CUR NPs possess much higher
cytotoxicity than free CUR, against MCF-7 breast cancer cells owing to sustained
drug release in a 96 h incubation time (Nosrati et al. 2018a). Furthermore, Kalita
et al. employed magnetic Fe3O4@zirconium phosphate core-shell NPs as efficient
vehicles for the delivery of curcumin to treat breast cancer (Kalita et al. 2016). A
similar study was conducted by Mancarella et al. which involves the designing of
functionalized Fe3O4 MNPs via coating with two different polymers: dextran and
poly(L-lysine). Further, the obtained nanohybrid was subjected to loading of
curcumin for the treatment of ovarian cancer (Mancarella et al. 2015).
In drug delivery stream, the transfer of therapeutic agent to the brain is the most
challenging approach. But the development of such an approach is the need of the
hour due to the growing prevalence of brain cancers and low efficiency of the
available treatments. Nosrati et al. managed to develop MRI-monitored paclitaxel
(PTX) delivery vehicle across the blood-brain barrier. In the current method, L-
aspartic acid-coated IONPs were fabricated, and further these were conjugated by
PTX, PEG (polyethylene glycol), and GSH (glutathione) for enhancing the brain
delivery
of
PTX.
Furthermore,
the
biocompatibility,
cytotoxicity,
and
hemocompatibility of the developed drug system were monitored by MRI (Nosrati
et al. 2018a).
