Used in biomedical applications such as targeted drug delivery, where the silica coating allows for easy functionalization with drugs or biomolecules while preventing aggregation and enhancing biocompatibility.

Employed in magnetic separation techniques to isolate DNA, RNA, or specific proteins from complex mixtures due to the high surface area and ease of recovery using an external magnetic field.

Applied in diagnostic assays and biosensors for rapid detection of pathogens or biomarkers, including immunoassays where particles are conjugated with antibodies to detect target antigens in blood or bodily fluids.

Also utilized in catalysis, where the SiO2 shell stabilizes the magnetic core and provides a platform for anchoring catalysts, enabling easy catalyst recovery and reuse.

Common in environmental remediation for removing heavy metals or organic pollutants from water through adsorption, followed by magnetic retrieval.

Additionally, used in automated laboratory systems because the particles can be controlled and separated without centrifugation or filtration, speeding up processes and reducing contamination.
