Descrizione generale

Poly(ethylene glycol) methyl ether thiol (mPEGthiol) is a thiol-terminated biocompatible polymer widely used in the surfacefunctionalization of gold nanoparticles. Thiol moieties bind with high affinityto gold surfaces by forming a self-assembled monolayer (SAM) through thecovalent thiolate–metal bond. mPEG thiol-coated Au nanoparticles findapplication in the fields of biosensors and drug delivery systems.

Applicazioni

Poly(ethylene glycol) methyl ether thiol-coated Au nanoparticles can be used for the determination of melamine T. by an optical method. It can also be used to fabricate switchable super-wetting membranes foroil/water separation.

The use of conductive nanoparticles (NPs) was previously proposed as a way to locally amplify the electric field (EF) intensity at the cell membrane to enhance cell electroporation. To achieve this, a close distance between the NPs and the cell

Antibody-coated nanoparticles have recently attracted considerable attention, with the focus falling on diagnostics. Nevertheless, controlled antibody bioconjugation remains a challenge. Here, we present two strategies of bioconjugation with the aim of evaluating the best approach for the coupling of antibodies

Articoli

Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.

Designing biomaterial scaffolds mimicking complex living tissue structures is crucial for tissue engineering and regenerative medicine advancements.

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.
