Application
Bildet ein Aminopropylderivat aus Glas, das als Adsorbens in der Affinitätschromatographie verwendet wird. Wird für die Zubereitung von positiv geladenen Objektträgern verwendet, die sich für den Einsatz in verschiedenen immunhistochemischen und in-situ-Hybridisierungsverfahren eignen.[1] (3-Aminopropyl)triethoxysilan wurde kürzlich für die Zubereitung von farbstoffdotierten Siliciumnanopartikeln verwendet und zeigte minimale Aggregation und minimale unspezifische Bindung an Biomoleküle.[2]
Für die Präparation einer Reihe von ternären Verbindungen zur Herstellung von Polyimid/SiO/Polydiphenylsiloxan-Kompositfolien mit guter optischer Transparenz.[3]
Self-assembled Monolayer (SAM) aus APTES kann verwendet werden, um die Adhäsion von Graphenflocken und SiO2 zu verbessern, damit ein besserer Kontakt mit den Metallelektroden erzielt wird. Diese Elektroden können als elektroresponsive Tools für Biosensoranwendungen eingesetzt werden.[4] Sie eignen sich für die Funktionalisierung von Silandiazirin in faseroptische Biosensoranwendungen.[5] Mittels APTES kann die Oberfläche von Hollow Microcarriers (HMC) modifiziert werden, um deren Verwendung für regenerative Medikamente und rekombinante Zellen in der Biopharmazeutik zu ermöglichen.[6]

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

Do you have any indications of what mass proportion I should use so that functionalization occurs between 3-APTES and an inorganic material, such as graphite?
1 answer-
Typically, a mass proportion of 1-2 wt% of APTES is recommended for effective functionalization. However, please note that APTES may not effectively bind to pristine graphite, and surface modification of the graphite may be necessary to enhance the functionalization process.

Kann APTES eine dauerhafte chemische Bindung mit der Oberfläche von fused silica eingehen? Falls ja, durch welchen Mechanismus erfolgt die Anbindung an das Siliziumdioxid? Wir möchten es als Haftvermittler für eine CYTOP-Beschichtung verwenden.
1 answer-
Yes, APTES can bond with fused silica. Fused silica, like silica gel, has hydroxyl (–OH) groups on its surface. When APTES is introduced to the fused silica surface, it undergoes hydrolysis. The ethoxy groups (–OEt) in APTES react with water, forming silanol groups (–Si–OH). The newly formed silanol groups can then react with the hydroxyl groups on the fused silica surface. This reaction leads to the formation of siloxane bonds (–Si–O–Si–), resulting in a covalent attachment of APTES to the fused silica.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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

Can this product be used to silanize a surface by using silane deposition via gas-phase evaporation?
1 answer-
This material has not been tested for use in silane deposition. APTES is referenced in the literature frequently in the vapor phase deposition of biosensors. The suitability would have to be determined experimentally.
Please see the links below to review examples of this process:
