What is the emission wavelength and host matrix of the Atomfair PEG-COOH-modified upconverting nanoparticles?

The emission wavelength is 804 nm and the host matrix is NaYREF4, as listed in the technical specifications of the product.

What solvent is the product supplied in, and what does the PEG-COOH modification indicate?

The product is supplied in water solvent. The PEG-COOH modification indicates the presence of carboxylic acid groups on the nanoparticle surface, enabling further functionalization.

What parameters should be confirmed before ordering the PEG-COOH-modified upconverting nanoparticles?

According to the selection notes, the concentration, solvent, emission color, and package size should be confirmed before quotation to ensure the correct configuration.

Assessment

This PEG-COOH-modified upconverting nanoparticle (NaYREF4, 35 nm, 804 nm emission) provides near-infrared excitation with water-based dispersion, enabling deep-tissue imaging with reduced autofluorescence, but requires careful handling to maintain colloidal stability and consistent optical output.

Positive

Near-infrared excitation for deep tissue: Emission at 804 nm (NIR) allows deeper penetration in biological samples with lower background autofluorescence compared to visible-light emitters, improving signal-to-noise in imaging applications.
Water-based dispersion for biocompatibility: Solvent is water, facilitating direct integration into aqueous biological assays and reducing the need for organic solvent handling or phase-transfer steps.

Trade-offs

Colloidal stability requires controlled storage: As a water-dispersed nanoparticle, aggregation may occur over time or under temperature fluctuations; proper storage conditions must be maintained to preserve particle size and optical properties.
Fixed emission wavelength limits multiplexing: The 804 nm emission is fixed by the NaYREF4 host and dopant composition; users requiring multiple distinct NIR channels must select different nanoparticle formulations, increasing procurement complexity.
