Modified rice straw/Fe3O4/polycaprolactone nanocomposites (ORS/Fe3O4/ PCL-NCs) have been prepared for the first time using a solution casting method. The RS/Fe3O4-NCs were modified with octadecylamine (ODA) as an organic modifier. The prepared NCs were characterized by using X-ray powder diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Thermogravime...

Multifunctional folic acid conjugated BSA@Fe3O4 microcapsules (FA-BSA@Fe3O4 MCs) have been prepared successfully based on the sonochemical method. The as-synthesized FA-BSA@Fe3O4 MCs have a suitable size range for biomedical applications, and a high loading capacity for water-insoluble drugs. Furthermore, FA-BSA@Fe3O4 MCs show excellent magnetic properties. Cytotoxicity tests indicate that FA-B...

Fe(3)O(4) nanoprisms, synthesized by a solvothermal process, exhibited crystal plane dependent electrochemical activities, which opens an approach to nanoscale materials with controlled electrochemical properties.

We present a systematic study on the preparation, characteration and potential application of Fe3O4 and Fe3O4@SiO2 nanoparticles. Fe3O4 nanoparticles of controllable diameters were successfully synthesized by solvothermal system with tuning pH. The magnetic properties of nanoparticles were measured by vibration sample magnetometer. Fe3O4@ SiO2 nanoparticles were obtained via classic Stöber proc...

The Fe3O4/CeO2 magnetic photocatalyst was prepared by coating directly onto the surface of magnetic Fe3O4 particles. However a direct contact of CeO2 onto the surface of magnetic Fe3O4 particles presented unfavorable heterojunction, thus the SiO2 barrier layer between magnetic Fe3O4 and CeO2 was prepared as a core-shell stucture to reduce the negative effect by combining three steps of the hydr...

The FeCo/Fe3O4 nanocomposite was synthesized using the hydrothermal approach, in which the FeCo alloy and Fe3O4 are formed by one step. The structure of the FeCo/Fe3O4 nanocomposite was characterized by means of Scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray energy-dispersive spectrometer spectroscopy (EDX). They show that the mass ratio of FeCo/Fe3O4 strongly depends on ...

Chitosan functionalized Fe3O4-Au core shell nanoparticles have been prepared using a two-step wet chemical approach using NaBH4 as reducing agent for formation of Au in ethylene glycol. X-ray diffraction studies shows individual phases of Fe3O4 and Au in the as prepared samples with crystallite size of 5.9 and 11.4 nm respectively. The functionalization of the core-shell nanostructure with Chit...

Multifunctional nanocomposites that have multiple therapeutic functions together with real-time imaging capabilities have attracted intensive concerns in the diagnosis and treatment of cancer. This study developed epidermal growth factor receptor (EGFR) antibody-directed polydopamine-coated Fe3O4 nanoparticles (Fe3O4@PDA NPs) for magnetic resonance imaging and antitumor chemo-photothermal thera...
