Iron Oxide/Silicon Oxide/Titanium Oxide Core-Shell Nanoparticles

Introduction

Iron oxide/silicon oxide/titanium oxide (Fe₃O₄/SiO₂/TiO₂) core-shell nanoparticles are a novel class of composite nanomaterials that combine the unique properties of iron oxide (Fe₃O₄), silicon oxide (SiO₂), and titanium oxide (TiO₂). These nanoparticles exhibit a core-shell architecture that synergistically integrates the characteristics of the individual components, leading to enhanced stability, multifunctionality, and performance across a wide range of applications, particularly in biomedicine, catalysis, environmental remediation, and sensing.

The core-shell design enables the optimization of specific properties by leveraging the strengths of each material:

Iron oxide (Fe₃O₄) core: Provides superparamagnetic properties.

Silicon oxide (SiO₂) shell: Offers chemical stability, biocompatibility, and surface functionalization.

Titanium oxide (TiO₂) outer layer: Contributes photocatalytic activity, biocompatibility, and mechanical strength.

This core-shell structure makes Fe₃O₄/SiO₂/TiO₂ nanoparticles highly versatile and suitable for use in applications that require magnetic properties, optical responses, and surface versatility. The multi-layered design also ensures that the nanoparticles possess a balance of biocompatibility, thermal stability, and chemical resistance, making them particularly promising for both in vitro and in vivo applications.
