Description générale

Les sels d'or (HAuCl4 3H2O) présentent une toxicité embryonnaire plus faible qu'un certain nombre d'autres nanoparticules à applications biomédicales.

Application

Le chlorure d'or(III) trihydraté peut être utilisé dans la fabrication d'aptacapteurs de Staphylococcus aureus colorimétriques.[1] Il peut être réduit à l'aide de racines de Polygala tenuifolia (agent réducteur de couleur verte) pour former des nanoparticules d'or (AuNP).[2]

Questions

1–8 of 8 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  4. I purchased this product and it seems to dissolve when weighing. Probably from the moisture in air. What is the recommended handling procedure for the salt?

    1 answer

    1. The product is very hygroscopic as well as light-sensitive. The product must be stored in a dry environment in a tightly closed container. Do not expose the product to air for extended periods of time, including during the weighing process.

      If you experience any continued handling problems please contact Technical Service for troubleshooting: navigate to the link https://www.sigmaaldrich.com/techservice, click on "Report Product Issues" under the Products Section with all the required information so that a member of the team can reach out to assist further.
