We extend the typical analysis of the extinction spectrum of magnetic core NPs by solving Mie theory with a frequency dependent susceptibility and considering the effect of Eddy currents in order to obtain the size distribution of the cores and the coating layers.

Vascular inflammation plays a crucial role in the progression of various pathologies, including atherosclerosis (AS), and thus it has become an attractive therapeutic target. The protocatechuic acid (PCA), one of the main metabolites of complex polyphenols, is endowed with anti-inflammatory activity, but its formulation into nanocarriers may increase its bioavailability. In this study, we developed and characterized dextran shell‒iron oxide core nanoparticles loaded with PCA (MNP-Dex/PCA) and assessed their cytotoxicity and anti-inflammatory potential on cells acting as key players in the onset and progression of AS, namely, endothelial cells (EC) and monocytes/macrophages. The results showed that MNP-Dex/PCA exert an anti-inflammatory activity at non-cytotoxic and therapeutically relevant concentrations of PCA (350 μM) as supported by the reduced levels of inflammatory molecules such as MCP-1, IL-1β, TNF-α, IL-6, and CCR2 in activated EC and M1-type macrophages and functional monocyte adhesion assay. The anti-inflammatory effect of MNP-Dex/PCA was associated with the reduction in the levels of ERK1/2 and p38-α mitogen-activated protein kinases (MAPKs) and NF-kB transcription factor. Our data support the further development of dextran shell-magnetic core nanoparticles as theranostic nanoparticles for guidance, imaging, and therapy of vascular inflammation using PCA or other anti-inflammatory compounds.

Different types of functionalized polymer magnetic core with diameters of 10-20 nm were prepared by condensation polymerization. Bi-layered polymer magnetic core nanoparticles were prepared by coating of magnetic core hydrophobic polymer shell composites of magnetic polyvinylbenzyl chloride with another layer. The second layer consists of 3-amino-1-propanol, butyl-l, 4-diamine or hexamethylenediamine The morphology and size of the magnetic polymer nanoparticles were characterized by TEM. The structure was characterized by IR, TGA and chemical stability against concentrated hydrochloric acid. The magnetic nanocomposites with hydrophilic behavior were easily separated by magnetic field and gives enhancing for using as nanocarrier in bioapplications.
