Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Hello, I want to know if I can add CTAB (cétyltriméthylammonium bromide) to this solution and expect efficient adsorption with the AuNPs without interference with the already present stabilizer ? Thanks in advance
1 answer-
There have not been previous attempts on adsorption of non-thiolated ligands to the surfactant stabilized gold nanoparticles. It is difficult to say to what extent the surfactant may influence the adsorption of CTAB to the particles.
Please test this by transferring 1 mL of gold nanoparticle suspension into a 1.5 mL centrifuge tube, centrifuge it at 17000 x g for 25-30 minutes, remove the supernatant, and resuspend the particles in a solution of water and CTAB (<1% v/v). If the sample appears to aggregate, then this will be a sign that the reagent is not compatible with the particles.

What diluent should be used to dilute gold nanoparticle?
1 answer-
This product is prepared as a susupension in a citrate buffer. It can be further diluted with water. Avoid diluting further with buffers containing other electrolyte salts such as sodium chloride. Due to the gold nanoparticle surface charge, aggregation and color changes will occur.

Do I need to wash my gold nanoparticles?
1 answer-
For most applications, our gold nanoparticles can be used without any additional washing steps. If you have a sensitive application that requires additional washing the best way to do so is by either centrifugation or filtration.
