Cobalt Cadmium Selenium Core-Shell Nanoparticles

Applications

Biomedical Imaging and Diagnostics

Fluorescence Imaging: The optical properties of CdSe quantum dots enable Co-Cd-Se core-shell nanoparticles to be used in in vivo and in vitro fluorescence imaging. These nanoparticles can be used as biomarkers for cell tracking, tissue imaging, and diagnostic purposes.

Magnetic Resonance Imaging (MRI): The Cobalt core provides strong magnetic properties, which can be harnessed for MRI applications. The Co-Cd-Se core-shell nanoparticles could be used as contrast agents to enhance MRI images, particularly for tumor imaging or targeted imaging.

Biosensing: Due to their optical and magnetic properties, Co-Cd-Se nanoparticles can be used in biosensors to detect a variety of biological markers, including proteins, nucleic acids, and pathogens. The fluorescent signal from the CdSe shell can be monitored and quantified in biosensing assays.

2. Drug Delivery

Magnetic Targeted Drug Delivery: The Cobalt core enables the Co-Cd-Se nanoparticles to be manipulated with an external magnetic field, allowing for targeted drug delivery to specific locations in the body. The CdSe shell can also be functionalized with targeting ligands to increase selectivity for specific cells or tissues, such as cancer cells.

Controlled Release Systems: The magnetic properties of the Co core can be used to trigger the release of drugs from the nanoparticles at specific sites. The optical properties of the CdSe shell can be used to monitor the release process in real time.

Catalysis

Electrocatalysis: Co-Cd-Se core-shell nanoparticles can be used in electrocatalytic applications such as water splitting, CO₂ reduction, and hydrogenation reactions. The Co core can act as an active site for catalysis, while the CdSe shell can help in charge separation during photocatalytic reactions under light irradiation.

Photocatalysis: The CdSe shell can absorb light and generate electron-hole pairs, making Co-Cd-Se nanoparticles efficient for photocatalytic reactions, such as water splitting for hydrogen production or pollutant degradation.

Magnetic Separation

Due to the strong magnetic properties of the Cobalt core, Co-Cd-Se core-shell nanoparticles can be used in magnetic separation techniques. They can be used for the removal of toxic ions, pathogens, or organic pollutants from water or biological systems. This is particularly useful in environmental remediation and biosafety applications.
