Název v původním jazyce

Mn-Zn ferrite nanoparticles coated with mesoporous silica as core material for heat-triggered release of therapeutic agents

Popis výsledku v původním jazyce

Hydrothermal synthesis was employed to prepare three samples of Mn-Zn ferrite nanoparticles with the mean size of crystallites of 12–14 nm, whose compositions were accurately determined by X-ray fluorescence spectroscopy to Mn0.82Zn0.21Fe1.97O, Mn0.70Zn0.31Fe1.99O4, and Mn0.62Zn0.41Fe1.97O4. The X-ray diffraction and SQUID magnetometry were used to determine the spinel structure and ferrimagnetic properties of the samples. AC field heating experiments were performed on particles dispersed in glycerol to evaluate the specific absorption rate. Cation distribution was determined in 10-nm sized Mn0.6Zn0.4Fe2O4 particles. Small clusters of Mn-Zn ferrite crystallites were coated with mesoporous silica. The mesoporous shell was loaded with rhodamine B as a hydrophilic model compound. The shell was sealed by a temperature-sensitive gatekeeper to control the release.
