General description

Silica coated manganese ferrite nanoparticles, 100nm particle size, 0.1 wt% in water, is designed by coating a silica shell on Manganese ferrite nanoparticles (NPs), enabling the water-solubility and biocompatibility of the NPs. The coating provides a protective and functional surface layer to the manganese ferrite nanoparticles, offering various advantages and potential applications in research work.

Application

Silica coated manganese ferrite nanoparticles find applications in the research areas of targeted drug delivery and magnetic resonance imaging (MRI) applications. The particles exhibit superparamagnetic behavior suitable for MRI contrast agents. In a study, silica-coated manganese ferrite nanoparticles has been found as a highly efficient T2 contrast agent compared to other reported nanoparticles justifying their potential for MRI based diagnosis of cancer. Studies found Silica coated manganese ferrite nanoparticles to be efficient, selective, and reusable adsorbents for methylene blue (MB) removal, which is a pollutant implicated in health issues, such as eye irritation and itchy skin as well as respiratory and digestive problems and is commonly used as a dye in the textile industry, for tissue staining, and in the leather tanning industry.
