Properties 

Silver nanoparticles are a great alternative to gold nanoparticles if absorption maximum is desired in between 400-500nm. Absorption in this lower range also allows for an increased dynamic range when developing multiplex experiments.

Cytodiagnostics silver nanoparticles are made using a unique proprietary protocol resulting in monodisperse particles and a narrow size distribution (CV <13%). This translates to improved performance in your experiment. In addition, core size batch-to-batch variation is small ensuring that you always end up with the same product. 

Storage

Store product in the dark at 4°C. 

Do NOT freeze. Freezing causes irreversible aggregation of the silver nanoparticles. 

When stored as specified the product is stable for at least 6 months.

Precautions and Disclaimer

This product are for R&D use only, not for drug, household, or other uses.
