Description

Mpeg-Silane Mw 2000 Da is a bifunctional polymer coupling agent, combining the hydrophilic, non-fouling properties of methoxy polyethylene glycol (mPEG) with the reactive silane functionality for covalent surface attachment. This unique hybrid structure is engineered to create stable, biocompatible, and low-fouling surfaces on a variety of inorganic substrates. It is essential for manufacturers in the biomedical, pharmaceutical, and advanced materials sectors seeking to improve the performance and longevity of their products through surface modification.

Application

• Biomedical Device Coating: Used to create stealth, protein-resistant surfaces on implants, surgical tools, and diagnostic devices to reduce biofouling and improve biocompatibility.
• Drug Delivery System Functionalization: Employed to modify the surface of nanoparticles, liposomes, or micelles, enhancing their circulation time in the bloodstream by imparting "stealth" properties.
• Chromatography Media: Applied to modify silica-based stationary phases for HPLC to reduce non-specific binding and improve separation efficiency for sensitive biomolecules.
• Biosensor Surface Chemistry: Serves as a linker to immobilize biomolecules (e.g., antibodies, enzymes) onto sensor chips while minimizing background noise.
• Anti-fog & Anti-fouling Coatings: Formulated into coatings for optical lenses, marine surfaces, or membranes to prevent adhesion of water, proteins, or organisms.
• Adhesive & Sealant Modification: Incorporated into formulations to improve adhesion to glass, metal, or ceramic surfaces while maintaining flexibility and moisture resistance.

Quality Control

Our Mpeg-Silane Mw 2000 Da is produced under a quality management system. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, functional group integrity, and purity. Certificates of Analysis (COA) detailing key parameters such as assay, degree of substitution, and solvent content are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its hygroscopic and moisture-sensitive nature. Allow the sealed container to reach room temperature before opening to prevent condensation and hydrolysis.
