The authors report a systematic investigation on different surfactant-functionalized superparamagnetic iron oxide nanoparticles (SPIONs) in order to explore the possibility of tuning the particle size by choosing an appropriate amphiphilic mol. By combining small-angle neutron scattering and dynamic light scattering, a description of the functionalized SPION structure was obtained. The relationship between crit. micelle concn. and the efficiency in coating the SPION surface was established. A lack in the formation of a compact shell led to clusters formation.

Abstract
The authors report a systematic investigation on different surfactant-functionalized superparamagnetic iron oxide nanoparticles (SPIONs) in order to explore the possibility of tuning the particle size by choosing an appropriate amphiphilic mol. By combining small-angle neutron scattering and dynamic light scattering, a description of the functionalized SPION structure was obtained. The relationship between crit. micelle concn. and the efficiency in coating the SPION surface was established. A lack in the formation of a compact shell led to clusters formation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
