Abstract
To enable reliable quantification of magnetic nanoparticles, new methods to prevent interactions of particles with their physiological environment are necessary. An innovative approach are SMART RHESINs, where conventional nanoparticles are encapsulated in hollow nanospheres. Here, a detailed study on Perimag® based SMART RHESINs has been performed utilizing critical offset magnetic particle spectroscopy (COMPASS) to show that the influence of the surrounding medium, which was varied in viscosity, on the particle system can be suppressed using SMART RHESINs.
