“…Subsequently, the Rietveld refinement allowed for assessing the average crystallite size and the unit cell parameters of the two types of the obtained microspheres (Table 2). As can be seen, the diffractograms demonstrate the formation of magnetite in the Fd-3m cubic crystal system as the unique mineralogical phase through the characteristic Miller indices (JCPDS 04-008-4511 [37]). Furthermore, the considerably high intensity values for each diffraction peak prove a high degree of crystallinity of the microspheres, as compared to nanoscaled magnetite [38][39][40].…”

Since cancer incidence is constantly increasing, novel and more efficient treatment methods that overcome the current limitations of chemotherapy are continuously explored. In this context, the aim of the present study was to investigate the potential of two types of magnetite microspheres as drug delivery vehicles for the controlled release of rosmarinic acid (RA) in anticancer therapies. The magnetite microspheres were obtained through the solvothermal method by using polyethylene glycol (PEG) with two different molecular weights as the surfactant. The physicochemical characterization of the so-obtained drug delivery carriers involved X-ray diffraction (XRD) coupled with Rietveld refinement, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), dynamic light scattering (DLS) and zeta potential, and UV–Vis spectrophotometry. The magnetite-based anticancer agents were biologically evaluated through the ROS-Glo H2O2 and MTT assays. Results proved the formation of magnetite spheres with submicronic sizes and the effective RA loading and controlled release, while the biological assays demonstrated the anticancer potential of the present systems. Thus, this study successfully developed a promising drug delivery alternative based on magnetite that could be used in the continuous fight against cancer.

“…Instead, the research into magnetic aerogels is still scarce and only some reports describe the formation of magnetic aerogels. [31][32][33][34][35] Anastasova et al 33,35 as well as Ganonyan et al 34 describe the synthesis of magnetite aerogels with the use of propylene oxide, following a sol-gel approach. In addition to that, Altenschmidt et al 36 described the aerogelation of polymer-coated iron oxide nanoparticles through addition of calcium cations.…”
