IDENTIFICATION OF MAGNETIC NANOPARTICLES BY SQUID BIOSUSCEPTOMETRIC SYSTEM


A method of non-invasive localization of magnetic nanoparticles injected in living animal is presented. Measuring the magnetic response of magnetic nanoparticles to AC magnetic field by using SQUID biosusceptometric system is investigated. Experimental measurements in vivo and in vitro show possibility of using this method as a non-invasive method of identification and distribution of magnetic nanoparticles in biological tissues of small animals.

Keywords:
magnetic nanoparticles, SQUID, superparamagnetism, experimental animal
