Iron Oxide/Titanium Oxide Core-Shell Nanoparticles

Introduction

Iron oxide/titanium oxide core-shell nanoparticles are composite nanomaterials that combine the magnetic properties of iron oxide (Fe₃O₄) with the photocatalytic and structural properties of titanium oxide (TiO₂). This core-shell architecture offers unique advantages by merging the functionalities of both materials, resulting in nanoparticles that exhibit multifunctionality suitable for a wide range of applications across biomedical, environmental, and industrial fields.

The iron oxide core (typically magnetite, Fe₃O₄) provides superparamagnetism, a property that allows the nanoparticles to be magnetized in the presence of an external magnetic field, and to lose their magnetization once the field is removed. This is particularly useful for applications in magnetic targeting, magnetic separation, and medical imaging.

The titanium oxide shell (TiO₂) contributes unique optical and chemical properties, including photocatalytic activity under UV light, which is valuable for environmental cleanup and disinfection. Additionally, TiO₂ imparts mechanical strength, chemical resistance, and biocompatibility.

The combination of these two materials into a core-shell structure offers synergistic effects—the iron oxide core provides magnetic functionality, while the titanium oxide shell enhances photocatalytic activity, stability, and surface reactivity. The resulting nanoparticles can be optimized for a variety of high-performance applications, such as catalysis, drug delivery, environmental remediation, and biosensing.
