Administration routes can greatly influence the pharmacokinetics, biodistribution and toxicity profile of the iron oxide nanoparticles. The purpose of this study was to investigate on a rat model the effect of three main administration routes of an aqueous dispersion of Fe3O4/salicylic acid magnetic nanoparticles (SaMNPs) on the pattern of their intravisceral storage. In order to identify the SaMNPs aggregates in the viscera we used Perl’s Prussian blue stain. Specific tissue or cell targeting for SaMNPs deposits can be obtained by either of the three delivery systems employed in our study. The aerosol-mediated delivery is recommended for pulmonary and cardiac tissues targeting, the intravenous route is preferable for hepatic and renal tissues targeting and the intragastric administration is the recommended route for SaMNPs delivery to the hepatic, renal and cardiac tissues.
