How does the 804 nm emission wavelength of these oil-dispersible core-shell upconverting nanoparticles compare to shorter wavelength emitters for deep tissue imaging applications?
The 804 nm emission falls within the near-infrared biological window, enabling deeper tissue penetration than visible upconversion emissions. The core-shell architecture (NaYReF4 core, NaYF4 shell) minimizes surface quenching, preserving upconversion efficiency in the NIR. However, detection requires NIR-sensitive photodetectors, which may involve a trade-off in sensitivity compared to visible detectors.
Can these oil-dispersible upconverting nanoparticles be used directly in aqueous biological assays without additional surface modification?
No, the nanoparticles are supplied in cyclohexane and are oil-dispersible, meaning they are optimized for hydrophobic environments. Direct addition to aqueous media will cause aggregation and loss of colloidal stability. For biological applications, a phase transfer step or surface functionalization with hydrophilic ligands is required to render them water-dispersible.
What handling and storage precautions are necessary for this 10 mg oil-dispersible upconverting nanoparticle product to maintain its optical properties?
The product is a dispersion in cyclohexane. Store at 4°C in a sealed, light-protected container to prevent solvent evaporation and photodegradation of the upconversion emission. The core-shell NaYReF4@NaYF4 structure is chemically stable, but avoid exposure to oxygen or moisture over extended periods. Vortex or sonicate gently before use to ensure uniform dispersion, as precipitation may occur over time.
This oil-dispersible core-shell upconverting nanoparticle (model AF-UCNNIR10MGOIL) emits at 804 nm under near-infrared excitation, with a ~30 nm particle size and NaYReF4(core)@NaYF4(shell) composition, supplied as 10 mg in cyclohexane for research luminescence applications.
Positive
- Core-shell architecture for stability: The NaYReF4(core)@NaYF4(shell) structure enhances photostability and reduces surface quenching, improving upconversion efficiency in oil-phase dispersions.
- NIR excitation reduces background: Emission at 804 nm under near-infrared excitation minimizes autofluorescence in biological or materials imaging, enabling higher signal-to-noise ratios.
Trade-offs
- Oil-dispersible only: Supplied in cyclohexane, this product is not water-dispersible; users must confirm solvent compatibility with their preparation workflow and may require phase-transfer steps for aqueous systems.
- Small package size limits use: The 10 mg package size is suitable for proof-of-concept studies but may require multiple orders for scaled experiments or repeated assays.
