It is best to store the particles in the buffer solution provided. The particles can be dried down and reused, but there are important considerations to keep in mind. Drying gold nanoparticles can lead to aggregation, which may affect their size, shape, and overall functionality. The citrate ions help stabilize the nanoparticles in solution, and removing the solvent can disrupt this stabilization. If dried, the nanoparticles need to be re-dispersed in ultra-pure water. If drying is necessary, consider storing the nanoparticles in a controlled environment (e.g., desiccator) to minimize moisture and humidity, which can lead to aggregation.

Which gold nanoparticle size should I choose for my application?
1 回答-
The size of gold nanoparticle to use is very depandent upon the intended application. Generally, smaller particles offer better sensitivity in applications such as immunogold labeling due to less steric hindrance and the ability to bind more gold nanoparticles to the desired target. Small gold nanoparticles are less visible than larger particles, however, which must also be taken into account.As an application example, particles with a size between 30-50nm are particularly useful for the development of rapid tests such as lateral flow assays.

How does the storage temperature relate to shipping conditions?
1 回答-
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 回答-
No, the Gold nanoparticles should not be frozen. If frozen, the gold nanoparticles will irreversibly aggregate, turning the solution clear.

Do I need to wash my gold nanoparticles?
1 回答-
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.

My gold nanoparticles settle out of solution upon storage. Is this normal?
1 回答-
Settling of gold nanoparticles on the bottom of the storage flask is completely normal and is especially common for larger sized particles, which settles at greater speed. Settling does not affect the performance of the particles. Prior to use, simply swirl the solution to properly disperse your gold nanoparticles and obtain a homogenous solution.
