General description

金ナノ粒子（AuNP）は準動的な物質であり、さまざまな生物医学、電気化学、エネルギーを基盤とする用途に商業利用されています。金ナノ粒子は比表面積が大きく、電気伝導度が高く、毒性が低いなどの特性があり、安定性が極めて高いです。

Application

オリゴヌクレオチドやポリエチレングリコールなどのチオール化リガンドの吸着に適しています。また、高い安定性を有することから、この金ナノ粒子は物理的、光学的用途への利用も可能です。注意：この製品はタンパク質吸着への利用には適していません。タンパク質やその他リガンドの吸着には、「gold nanoparticles stabilized in PBS」製品が最適です。

この材料は極めて高い単分散性(サイズと形状の変動係数：<12%)を示し、表面の反応性が大幅に向上しています。その応用例は、表面増強型ラマン散乱ナノプローブ、センサ/検出、生物学的ターゲティング、プラズモンナノ構造、およびナノスケールパターニングなどがあります。
AuNPは以下の用途に用いられています：
  • 薬剤放出剤として、生物医学で応用
  • 界面化学と生体適合性に優れていることから、癌放射線療法に
  • 電気化学的バイオセンシングシステムに

質問

1–10/21 質問  

  1. How long can I use this product after opening? Under appropriate storage temperature?

    1 回答

    1. This product is supplied as an aqueous suspension. It can be stored at 2 - 8 °C in its original container upon opening.

      Products that are robust in nature and extremely stable, in the original unopened container, are not assigned an expiration date or retest schedule. These products will have no dating reported on either the label or the Certificate of Analysis.

      Products that are not assigned an expiration or retest date are covered by a warranty period of 1 year from the date of product shipment.

      Full Product Dating Information may be reviewed at the link below: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/190/408/product-dating-information-ms.pdf?.

  2. What is the extinction coefficient/Molar Absorptivity of this product?

    1 回答

    1. For this product, the molar concentration is 9.93E-09 M. Based on an OD (optical density) of 1.00, the molar extinction coefficient is 1.01 X 10E8.

      役に立ちましたか？

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

    1 回答

    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/418/501/product-dating-information-06-25-mk.pdf

  4. How do you concentrate the 10nm gold nanoparticles in order to increase its OD?

    1 回答

    1. There is no guaranteed method to concentrate this product, as doing so may lead to aggregation of the nanoparticles rather than an increase in optical density (OD). Aggregation can adversely affect the properties and performance of the nanoparticles.

      役に立ちましたか？

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

    1 回答

    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

  6. How to calculate molarity of this Aunps solution?

    1 回答

    1. The molar concentration is 9.93E-09 M. This can be calculated using the weight concentration of 6.07E-02 and the molar mass of 6.11E+06.

      役に立ちましたか？

  7. 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 回答

    1. 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.

  8. at which concentration is the citrate buffer?

    1 回答

    1. This is a product of CytoDiagnostics, Inc. It is supplied in 0.1mg/ml citrate buffer supplemented with a proprietary stabilizing solution.

      役に立ちましたか？

  9. Is autoclave distilled water okay to use to dilute gold nanoparticle?

    1 回答

    1. Autoclaved, distilled water is suitable to use as a diluent for gold nanoparticles.

      役に立ちましたか？

  10. What diluent should be used to dilute gold nanoparticle?

    1 回答

    1. 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.
