Fe3O4 Nanoparticles in Targeted Drug/Gene Delivery Systems

Fe3O4 Nanoparticles in Targeted Drug/Gene Delivery Systems

Fe₃O₄ nanoparticles (NPs), the most traditional magnetic nanoparticles, have received a great deal of attention in the biomedical field, especially for targeted drug/gene delivery systems, due to their outstanding magnetism, biocompatibility, lower toxicity, biodegradability, and other features. Naked Fe₃O₄ NPs are easy to aggregate and oxidize, and thus are often made with various coatings to ...

Magnetic nanoparticles as targeted delivery systems in oncology

BACKGROUND Many different types of nanoparticles, magnetic nanoparticles being just a category among them, offer exciting opportunities for technologies at the interfaces between chemistry, physics and biology. Some magnetic nanoparticles have already been utilized in clinical practice as contrast enhancing agents for magnetic resonance imaging (MRI). However, their physicochemical properties a...

Surface-Modified Superparamagnetic Nanoparticles Fe3O4@PEG for Drug Delivery

In this work, we report on the synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, CTAB as cationic surfactant and butanol as a cosurfactant. Surface modification have been carried out by using poly(ethyleneglycol) (PEG). The structure,morphology, and magnetic properties of the products were characteriz...
