一般說明

这种纳米银粉由直径小于100 nm的金属银纳米颗粒组成。这些纳米银颗粒包被有质量浓度为0.2%的聚乙烯吡咯烷酮(PVP)。这种涂层有效地抑制了表面氧化,并增强了粉末在各种溶剂中的分散性。

纳米银粉在医学应用和医疗器械中得到了广泛应用。纳米银的表面积体积比增加、反应性提高,使其在现代生物医学应用中特别有价值,特别是在医疗器械涂层中。

應用

使用银纳米线配制水基油墨。[1]已对导致更多可洗脱物质的银纳米颗粒进行研究。[2] 对银纳米颗粒 (AgNPs) 的免疫佐剂作用进行了体外 和体内 研究 [3] 制造了基于银纳米颗粒的石墨环氧纳米复合材料。 [4] 有研究表明,AgNP 可通过增加血小板聚集和促凝血活性促进血栓形成。[5]已制备 AgNP 光致沉积的光纤传感器。[6] 含 Ag 和羟基磷灰石作为纳米添加剂的 PAN 纤维基纳米复合材料已有报道。 [7]

Questions

1–2 of 2 Questions  
  1. 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

  2. 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
