What is the trade-off between the 0.1 mg/mL concentration and the 2–5 nm particle size in terms of fluorescence output for this blue carbon quantum dot dispersion?
The source confirms a concentration of 0.1 mg/mL and a particle size of 2–5 nm, both of which are typical for blue-emitting carbon quantum dots. However, no quantitative relationship between concentration, particle size, and fluorescence intensity is provided. The product appears as a light blue solution, indicating visible blue fluorescence, but specific quantum yield or brightness data are not included in the description.
Can this water-soluble carbon quantum dot dispersion be directly integrated into polymer or organic solvent-based formulations without aggregation?
The dispersion is water-based with a solvent of water, so it is inherently compatible with aqueous systems. The source does not provide data on compatibility with organic solvents or polymer matrices. Users should anticipate potential aggregation or phase separation when mixing with non-aqueous media and verify compatibility through small-scale testing before full integration.
What storage and handling conditions are required to preserve the stability of this blue fluorescence carbon quantum dot dispersion?
The source advises matching the dispersion format to appropriate storage practice but does not specify exact temperature, light, or shelf-life requirements. Based on the water-soluble and light blue solution characteristics, typical laboratory storage at 4°C in the dark is recommended to minimize photodegradation and aggregation. Users should consult the manufacturer for validated stability data, as none are provided in the product description.
Water-soluble blue fluorescence carbon quantum dot dispersion (0.1 mg/mL, 50 mL, particle size 2–5 nm) evaluated for aqueous-phase optical labeling and nano-sensing applications, with water solubility enabling biocompatible integration but requiring careful volume handling and solvent compatibility considerations.
Positive
- Water-soluble dispersion: Pre-dispersed in water at 0.1 mg/mL, the quantum dots are immediately usable in aqueous-phase workflows without reconstitution, reducing preparation time and risk of aggregation.
- Blue fluorescence, 2–5 nm size: Particle size in the 2–5 nm range ensures quantum confinement effects for blue fluorescence emission, suitable for high-resolution optical imaging and fluorescence-based assays.
Trade-offs
- Low concentration dispersion: At 0.1 mg/mL, the dispersion provides limited mass per volume, requiring larger volumes or concentration steps for applications demanding higher quantum dot density.
- Aqueous-only solvent compatibility: The water-based solvent restricts direct use in organic or non-polar solvent systems, necessitating phase transfer or surface modification for integration with hydrophobic matrices.
