Brand: ATOMFAIR®
This water-based gold nanostar dispersion requires refrigerated storage at 4°C in a light-protected, sealed container to prevent aggregation and degradation. The product is intended for laboratory-scale R&D use and should be handled with appropriate personal protective equipment.
- Temperature Constraint: Store at 4°C refrigerated to maintain dispersion stability.
- Light Protection Constraint: Protect from light to avoid photochemical degradation of the nanostars.
- Container Sealing Constraint: Keep container sealed when not in use to prevent evaporation and contamination.
What are the concentration and dispersion medium for the AF-AUNST1056 10 mL gold nanostar dispersion?
The 10 mL packaging is a water-based dispersion listed with ultrapure water as the dispersion medium/stabilizer and a stated concentration of 50 ug/mL. It is supplied as star-shaped gold (CAS 7440-57-5, Au) in sealed laboratory dispersion packaging.
Can the AF-AUNST1056 gold nanostar dispersion be used in SERS, photothermal, and biosensing research?
Yes. The product is described as prepared for SERS and Raman sensing research, photothermal and near-infrared optical research, biosensing, imaging, and biomedical nanomaterial studies, as well as conductive paste, coating, and electrode development. It is a research-grade material intended for laboratory-scale R&D use, so confirm specifications before advanced or large-scale applications.
How should the AF-AUNST1056 10 mL gold nanostar dispersion be stored and handled?
Store the sealed dispersion at 4 C, protected from light, and keep it sealed. Handle it with appropriate personal protective equipment and refer to the SDS before use. The product is research grade and intended for laboratory-scale R&D use only.
The Gold Nanostar Dispersion 10mL (AF-AUNST1056) is a water-based, star-shaped gold nanoparticle suspension at 50 µg/mL, optimized for SERS, photothermal, and biosensing applications. Its branched morphology provides enhanced electromagnetic field localization at tips, but requires refrigerated, light-protected storage and careful handling to prevent aggregation.
Positive
- Star-shaped morphology for plasmonic enhancement: The branched nanostar geometry generates strong electromagnetic field hotspots at tips, significantly improving SERS signal amplification and photothermal conversion efficiency compared to spherical nanoparticles.
- Water-based dispersion for biocompatibility: Ultrapure water as the dispersion medium eliminates organic solvent interference, enabling direct use in biological assays, imaging, and biomedical nanomaterial studies without additional phase transfer steps.
Trade-offs
- Refrigerated light-protected storage required: The dispersion must be stored at 4°C and protected from light to prevent nanoparticle aggregation or photodegradation, necessitating dedicated cold storage and light-blocking containers in the lab.
- Research grade with limited stability data: As a research-grade material, the dispersion's long-term colloidal stability and batch-to-batch reproducibility are not guaranteed; users must confirm specifications and perform pre-experiment characterization.
