Product Description

Cadmium Selenide Cadmium Sulfur Silica Core Shell Nanoparticles Description

Cadmium Selenide Cadmium 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.



Customizable Optical Performance

These nanoparticles offer strongly tunable emission wavelengths, from 450 nm to 650 nm, allowing adaptation to diverse research and display needs. Color changes between orange, red, and yellow according to quantum dot size, providing visual cues and flexibility for specific scientific or industrial applications.


Surface Modification and Dispersibility

Silica surface functionalization enables bioconjugation, chemical linkage, and tailored suspension in either aqueous or organic solvents. Options such as -COOH, -NH2, and PEG allow compatibility with varied environments, from biosensing to optoelectronic device fabrication.


Safe Handling and Longevity

Given their cadmium content, these nanoparticles require careful handling according to research standard protocols. They are hazardous and regulated, yet if stored away from light and moisture in sealed containers, their shelf life ranges from 12-24 months, ensuring reliable availability for laboratory needs.

FAQ's of Cadmium Selenide Cadmium Sulphur Silica Core Shell Nano Particles:


Q: How can the particle size of Cadmium Selenide Cadmium Sulphur Silica Core Shell Nano Particles be customized for research applications?

A: Particle size, typically 10-50 nm, can be adjusted upon request during synthesis, enabling specific optical and dispersibility properties tailored for a researcher's target application.

Q: What is the recommended process for safely handling and storing these nanoparticles?

A: Since these nanoparticles contain toxic cadmium compounds, they should be handled in accordance with hazardous materials protocols-wear appropriate PPE, use fume hoods, and keep them in sealed glass vials or inert containers stored in a cool, dry, and light-protected environment.

Q: When is silica surface functionalization especially beneficial for these core-shell nanoparticles?

A: Silica surface functionalization is ideal when bioconjugation or stability in specific solvents is needed, such as in biomedical labeling or dispersing the nanoparticles in aqueous systems for fluorescence studies and biosensing.

Q: Where are these nanoparticles commonly applied within research and industry?

A: They are widely utilized in quantum dot displays, biosensing, imaging probes, optoelectronic devices, and photovoltaic cells, benefiting both in vitro and in vivo settings after suitable surface passivation.

Q: What benefits do these core-shell nanoparticles offer for fluorescence-based imaging and biomedical applications?

A: Strong and tunable photoluminescence allows precise wavelength emission for imaging, while robust core-shell structures and customizable surfaces provide high stability, targeted labeling, and improved compatibility with biological environments.

Q: How does surface modification influence dispersibility and application environments?

A: Surface modification, such as with -COOH or -NH2 groups, enables dispersibility in polar or non-polar solvents and tailors compatibility with aqueous or organic research environments, ensuring optimal nanoparticle performance in diverse applications.

Q: What is the shelf life and how does storage affect the longevity of these nanoparticles?

A: Shelf life ranges from 12-24 months when stored according to recommendations: in sealed containers, kept away from moisture and light, ensuring the stability of the quantum dot's photoluminescent properties and integrity.
