How many grams of gold nanoparticles in the 1 ml of 50nm gold nanoparticle suspension. Kindly provide this details as i need to know the diffusion rate of it.
1 answer-
This is a product of CytoDiagnostics, Inc. The 50 nm gold particles have a weight concentration of 44.5 ug/mL. This is an approximation as there is some degree of variability in particle size. See the image below to review the gold nanoparticle specification ranges.

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.

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.

Can the Gold nanoparticles be frozen?
1 answer-
No, the Gold nanoparticles should not be frozen. If frozen, the gold nanoparticles will irreversibly aggregate, turning the solution clear.
