Resumen

Magnetite nanoparticles (Fe₃O₄ NPs) coated with silicon dioxide (SiO₂) defined as Fe₃O₄@SiO₂ core-shells are a viable option for the development of addressable and multifunctional nanotargets; because of their superparamagnetic properties, molecular/biological anchor and biocompatibility in nanomedicine and theragnostics. In this work, we report Fe₃O₄@SiO₂ obtained by Stöber and sonochemical methods combination at low irradiation power (130 W, 1 h) with different volumes of tetraethylorthosilicate (TEOS). Fe₃O₄@SiO₂ results showed effects of diamagnetic silanol (Si-OH) layer as function of concentration over magnetic behavior.
