abstract = {A rational use of superparamagnetic iron oxide
nanoparticles (SPIONs) in drug delivery, diagnostics, and
other biomedical applications requires deep understanding of
the molecular drug adsorption/desorption mechanisms for
proper design of new pharmaceutical formulations. The
adsorption and desorption of the cytostatic Mitoxantrone
(MTO) to lauric acid-albumin hybrid coated particles SPIONs
(SEONLA−HSA) was studied by Fourier transform infrared
spectroscopy (FTIR), dynamic light scattering (DLS), surface
titration, release experiments and small-angle neutron and
X-ray scattering. Such MTO-loaded nanoparticles have shown
very promising results in in vivo animal models before,
while the exact binding mechanism of the drug was unknown.
SEONLA−HSA formulations have shown better stability under
drug loading in comparison with uncoated nanoparticle and
sustainable drug release to compare with protein solution.
Adsorption of MTO to SEONLA−HSA leads to decreasing of
absolute value of zeta potential and repulsive interaction
among particles, which points to the location of separate
molecules of MTO on the outer surface of LA-HSA shell.},
