Product Description

Cadmium Selenide Zinc Sulfur Silica Core Shell Nanoparticles Description

Cadmium Selenide Zinc Sulfur Silica Core Shell Nanoparticles is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Nanochemazone produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available, as is additional technical and safety (MSDS) data. Please contact us for information on lead time and pricing above.



Superior Photoluminescence and Quantum Yield

Featuring a high quantum yield of 30-80% and strong, tunable emission across the visible spectrum (450-650 nm), these core-shell nanoparticles are ideal for precision labeling, imaging, and optoelectronics. The careful engineering of CdSe/ZnS/SiO2 structure maintains brightness and stability during applications.


Customizable Surface Functionalization

The silica outer shell provides versatile chemical modification options, including amine, carboxyl, and PEG groups, enabling dispersion in both water and select organic solvents. This flexibility facilitates integration into various research protocols, from biomedical imaging to advanced materials science.


Robust Thermal and Solution Stability

These nanoparticles remain stable up to 300C and in solution for weeks under dark, refrigerated storage conditions. Their sealed packaging under inert atmosphere and recommended storage at 2-8C guarantee extended shelf life and product integrity for up to 18 months.


Safety and Handling Precautions

Due to the cadmium-based core, these quantum dots are classified as toxic-strict laboratory handling is vital. They are designated for research use only, not intended for in vivo applications, and should be stored in a desiccator away from sunlight and moisture.

FAQ's of Cadmium Selenide Zinc Sulfur Silica Core Shell Nanoparticles:


Q: How can I disperse Cadmium Selenide Zinc Sulfur Silica Core Shell Nanoparticles for my experiments?

A: These nanoparticles are offered as either colloidal dispersions or dry powders. Surface-functionalized versions (amine, carboxyl, or PEG groups) can be dispersed in water, while unmodified or hydrophobic forms are suited for organic solvents. Sonication may help achieve homogeneous suspensions in your chosen medium.

Q: What are the main applications of these core-shell nanoparticles?

A: They are primarily used in quantum dot labeling, fluorescence imaging, biosensors, nanodevice fabrication, and optoelectronics. Their tunable, bright emission enables precise detection and tracking in bio-imaging and analytical research, while their robust structure makes them suitable for photonic and electronic devices.

Q: When should I use surface-functionalized nanoparticles versus unmodified ones?

A: Surface-functionalized nanoparticles (with amine, carboxyl, or PEG groups) are beneficial for aqueous dispersibility and bio-compatibility, making them ideal for biological labeling and imaging. Unmodified nanoparticles are generally preferred for applications in organic media or material science, where functional groups may not be required.

Q: Where should the nanoparticles be stored to maintain quality and stability?

A: For longevity and stability, store the nanoparticles in a desiccator away from sunlight and moisture at 2-8C. Always keep the vials sealed under an inert atmosphere; when handled properly, shelf life extends to 12-18 months.

Q: How is the emission wavelength tuned in these nanoparticles?

A: The emission wavelength is primarily governed by the particle size during synthesis. Smaller particles emit towards the blue/violet region, while larger ones shift towards red. Custom sizes can be requested to match specific emission requirements.

Q: What safety considerations should be observed when working with these nanoparticles?

A: These quantum dots contain cadmium and are toxic if swallowed, inhaled, or contacted with skin. Always handle them in a well-ventilated lab, using proper safety gear (gloves, lab coat, goggles), and follow all protocols for hazardous materials disposal. They are strictly for research applications, not for use in or on humans or animals.

Q: What benefits do silica-coated CdSe/ZnS quantum dots offer compared to uncoated forms?

A: The silica shell enhances colloidal stability, provides chemical flexibility for surface modifications, and lowers toxicity risk by encasing the CdSe/ZnS core. It also improves compatibility with various solvents and bio-conjugation strategies, expanding their utility across diverse research fields.
