Advanced Optical Tunability for Research Applications

Cadmium Telluride Quantum Dots offer tunable emission wavelengths by varying their particle size, enabling precise adjustment from green to near-infrared light. This flexibility makes them ideal for sophisticated imaging techniques, sensor development, and optoelectronic research, providing scientists and engineers with customizable solutions for diverse experimental needs.

Surface Functionalization Enhances Bioconjugation

These quantum dots can be tailored with carboxyl, amine, or various functional groups to improve compatibility with biomolecules. This adaptability streamlines conjugation processes, enabling accurate tagging in bioimaging and biosensing applications. Hydrophilic modifications ensure excellent dispersibility in aqueous environments, further supporting biomedical use.

Safe Storage and Responsible Use

To maintain stability and performance, CdTe quantum dots should be stored at 2-8C, shielded from light, and sealed tightly. Given their toxicity, they must be handled in well-ventilated spaces and disposed of as hazardous waste according to local regulations. Strict adherence to safety protocols protects both users and the environment.

FAQs of Cadmium Telluride Quantum Dots:

Q: How should Cadmium Telluride Quantum Dots be stored to maximize shelf life and stability?

A: Store CdTe Quantum Dots at 2-8C in a tightly closed container, protected from light and moisture. Stability is retained for at least 12 months under these conditions. Avoid exposure to strong acids, bases, and oxidizing agents to prevent degradation.

Q: What benefits do CdTe Quantum Dots provide for bioimaging and sensor applications?

A: CdTe Quantum Dots offer tunable emission wavelengths and high quantum yields, allowing precise optical labeling and sensitive detection. Functionalization options facilitate bioconjugation with antibodies or other biomolecules, enhancing performance in bioimaging, diagnostics, and biosensors.

Q: When is it necessary to modify the surface of CdTe Quantum Dots, and what groups are typically used?

A: Surface modification is recommended for applications involving biological systems or aqueous media. Carboxyl and amine groups are commonly attached to increase hydrophilicity and provide binding sites for bioconjugation, improving compatibility with biological molecules and dispersibility in water or buffers.

Q: Where can CdTe Quantum Dots be utilized outside of biomedical applications?

A: Beyond biomedical use, CdTe Quantum Dots find applications in photovoltaics, optoelectronic devices, display technologies, and research on semiconductor nanomaterials. Their tuneable optical characteristics and crystalline microstructure support performance in solar cells, LEDs, and sensors.

Q: What precautions are required when handling CdTe Quantum Dots?

A: Due to the presence of toxic cadmium, handle the quantum dots in well-ventilated areas, preferably under a fume hood. Use appropriate personal protective equipment, and avoid inhalation, ingestion, or skin contact. Dispose of all waste according to local hazardous material regulations.

Q: How does particle size affect the emission wavelength and quantum yield of CdTe Quantum Dots?

A: The emission wavelength of CdTe Quantum Dots varies with particle size: smaller dots emit at shorter wavelengths (green), while larger dots shift toward longer wavelengths (red/near-infrared). The quantum yield also depends on size and surface modification, typically ranging between 30-70%.
