How does the 804 nm emission wavelength of these PEG-NH2-modified upconverting nanoparticles benefit deep-tissue imaging compared to shorter-wavelength emitters?
The 804 nm emission falls within the near-infrared biological transparency window, enabling deeper tissue penetration and reduced autofluorescence. This advantage is directly supported by the specified emission wavelength of 804 nm listed in the product specifications.
What surface functionalization is available on these PEG-NH2-modified upconverting nanoparticles for bioconjugation?
The PEG-NH2 modification provides primary amine groups on the nanoparticle surface, allowing covalent conjugation to biomolecules such as antibodies or peptides via standard carbodiimide chemistry. The solvent is water, confirming aqueous compatibility for biological assays.
What are the recommended storage conditions for maintaining the stability of these PEG-NH2-modified upconverting nanoparticles?
The product should be stored according to the intended preparation workflow; for the 20 mg package, it is recommended to protect from light and moisture, and to avoid freeze-thaw cycles if supplied as a dispersion in water. The description emphasizes confirming concentration, solvent, and package size before use.
PEG-NH2-modified upconverting nanoparticles with 35 nm particle size, NIR emission at 804 nm, and water dispersion, suitable for bioimaging and photonic applications requiring NIR-to-NIR upconversion.
Positive
- NIR emission for deep tissue imaging: Emission at 804 nm (near-infrared) enables deep tissue penetration with minimal autofluorescence, advantageous for in vivo bioimaging applications.
- PEG-NH2 surface functionalization: Amine-terminated PEG coating provides colloidal stability in aqueous media and reactive sites for bioconjugation to targeting ligands or biomolecules.
Trade-offs
- Research-grade with batch variability: Supplied as a research-grade product; batch-to-batch consistency in particle size, emission efficiency, and surface chemistry is not guaranteed for clinical or diagnostic use.
- No specified concentration or molar quantity: The product is supplied as 20 mg total mass in water, but concentration (mg/mL) is not stated, requiring additional characterization before use in quantitative assays.
