abstract = {Nanoparticles (NPs) are increasingly exploited as
diagnostic and therapeutic devices in medicine. Among them,
superparamagnetic nanoparticles (SPIONs) represent very
promising tools for magnetic resonance imaging, local
heaters for hyperthermia, and nanoplatforms for multimodal
imaging and theranostics. However, the use of NPs, including
SPIONs, in medicine presents several issues: first, the
encounter with the biological world and proteins in
particular. Indeed, nanoparticles can suffer from protein
adsorption, which can affect NP functionality and
biocompatibility. In this respect, we have investigated the
interaction of small SPIONs covered by an amphiphilic double
layer of oleic acid/oleylamine and
1-octadecanoyl-sn-glycero-3-phosphocholine with two abundant
human plasma proteins, human serum albumin (HSA) and human
transferrin. By means of spectroscopic and scattering
techniques, we analyzed the effect of SPIONs on protein
structure and the binding affinities, and only found strong
binding in the case of HSA. In no case did SPIONs alter the
protein structure significantly. We structurally
characterized HSA/SPIONs complexes by means of light and
neutron scattering, highlighting the formation of a
monolayer of protein molecules on the NP surface. Their
interaction with lipid bilayers mimicking biological
membranes was investigated by means of neutron reflectivity.
We show that HSA/SPIONs do not affect lipid bilayer features
and could be further exploited as a nanoplatform for future
applications. Overall, our findings point toward a high
biocompatibility of phosphocholine-decorated SPIONs and
support their use in nanomedicine.},
