What is the relative intensity ratio of the 545 nm and 660 nm emission peaks for these PEG-NH2-modified upconverting nanoparticles, and how does the 35 nm particle size affect upconversion efficiency?
The product listing specifies two emission peaks at 545 nm and 660 nm but does not provide their relative intensity ratio. The particle size is 35 nm, but no comparative efficiency data versus other sizes is given. Users should contact Atomfair for the technical datasheet to obtain quantitative performance metrics.
What are the PEG molecular weight and grafting density of the NH2 surface modification, and how do these parameters affect conjugation efficiency and colloidal stability in water?
The product description identifies the nanoparticles as PEG-NH2-modified and indicates water as the solvent, but does not specify PEG molecular weight, chain length, or grafting density. For surface characterization details that influence bio-conjugation and dispersion stability, users should request the technical specification from Atomfair.
What are the recommended storage conditions and shelf life for the 20 mg aqueous dispersion of these upconverting nanoparticles to maintain optical performance?
The product listing does not include specific storage conditions or shelf life. It advises confirming the format (powder or dispersion) and matching to intended workflow. Users should consult Atomfair directly for validated storage and handling protocols to preserve optical stability.
This PEG-NH2-modified upconverting nanoparticle (20 mg, 35 nm, NaYREF4) exhibits dual emission at 545 and 660 nm and offers amine surface functionality for bioconjugation, but requires careful format confirmation and is limited to research applications.
Positive
- Dual emission peaks for ratiometric detection: Two emission peaks at 545 and 660 nm enable ratiometric sensing or multiplexed imaging in a single excitation.
- PEG-NH2 surface for bioconjugation: Amino-functionalized PEG coating provides reactive sites for covalent attachment of antibodies, peptides, or other biomolecules.
Trade-offs
- Format dependency requires pre-order confirmation: Buyer must confirm whether the material is supplied as powder or dispersion, as workflow and storage conditions differ significantly.
- Research-grade only, no clinical validation: Product is labeled for research use only and has not been validated for diagnostic or therapeutic applications.
