一般說明

11-巯基十一烷酸(MUA)具有长链烷烃链和含羧基的硫醇,它们高度堆积并可形成自组装单层(SAM)。它可以修饰纳米颗粒的表面,以利于将其分散至基于水和溶剂的介质中。[1][2]

應用

通过通常在生物医学应用中使用的Murray置换反应,MUA可用于1-十二烷硫醇保护的金纳米颗粒(AuNPs)的羧酸官能化。[3]它也可通过创建具有高表面覆盖率的配体纳米组装体,来对铂纳米颗粒(PtNP)的表面进行修饰,从而用于表面增强拉曼光谱(SERS)分析。[4]单细胞生物芯片平台可以利用细胞附着技术进行开发,其中MUA会形成附着至单细胞的SAM。[5]MUA可用于制备四氟苯基活化的酯自组装单层膜,从而对胺修饰的寡核苷酸[6] 和DNA进行固定化。[7] 它还可用于为等离子生物传感器创建3D组装的金纳米结构。[8]

A tetrafluorophenyl (TFP) ester-terminated self-assembled monolayer (SAM) for the fabrication of DNA arrays on gold surfaces is described. Activated ester SAMs are desirable for biomolecule array fabrication because they readily react with amine-containing molecules to form a stable amide linkage.

Three-dimensional gold nanoarchitecture was fabricated by layer-by-layer (LbL) deposition of gold nanoparticles (AuNPs) and multiwalled carbon nanotubes (MWCNTs) on a glass substrate for a highly sensitive plasmonic biosensor using a conventional UV-vis instrument. Carboxyl-functionalized MWCNTs were reacted with 3-mercaptopropyltriethoxysilane (MPTES)

文章

Recent research highlights tunable properties of inorganic nanoparticles, driving interest in optoelectronics.

Self-assembled monolayers (SAMs) have diverse applications; article compares benefits of alkylthiolates on gold SAM systems.

Questions

1–2 of 2 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.

  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
