The methoxy groups of the silane hydrolyze and form strong covalent bonds with the native oxide layers present on ceramics (SiO2) or free (OH) groups on silicon carbide or boron carbide. To improve adhesion at the interface, introducing controlled roughening of the surface is advisable. A solution concentration in the range of 1–5% should provide sufficient effectiveness.

General description
(3-Glycidyloxypropyl)trimethoxysilane (GPTMS) is a high-purity, bifunctional organosilane designed for the seamless integration of biological molecules and organic polymers with inorganic substrates. This ≥98% purity grade is unique for its terminal epoxy (oxirane) ring, which enables "reagent-free" covalent bioconjugation via nucleophilic attack from amines, thiols, or hydroxyls. This reagent is the gold standard for stabilizing conductive polymers and creating 3D-networked hybrid scaffolds, offering a pH-selective reactivity profile that allows for controlled surface modification and superior optical clarity in thin-film applications.
Application
As a versatile molecular bridge, GPTMS is essential for engineering intelligent interfaces and stimuli-responsive systems that enable precise interactions at the intersection of nanotechnology, biology, and electronics.
• Reagent-Free Bioconjugation: Enables direct immobilization of proteins, enzymes, and amino-modified DNA onto surfaces without secondary cross-linkers like EDC/NHS. • Conductive Polymer Stabilization: Enhances the electrical stability and mechanical adhesion of PEDOT:PSS films in bio-electronic sensors and neural interfaces. • Tissue Engineering Scaffolds: Functions as a critical cross-linker in chitosan-silica hybrids, significantly improving mechanical stability and biomineralization for bone regeneration. • Nanocarbon Reinforcement: Surface-modifies carbon nanotubes (MWCNTs) to optimize dispersion and interfacial bonding in high-performance nanocomposites for medical implants. • Enzyme Immobilization: Functionalizes silica and magnetic nanoparticles to create high-surface-area biocatalytic platforms for diagnostic assays and pharmaceutical synthesis.

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.

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

I connected GPTMS synthetically to my lipid(APTES), now my lipid cannot be dissolved in chloroform, ethanol and methanol solutions, which was previously dissolved, what solvent should I use?
1 answer-
The solubility of the GPTMS/APTES sample has not been tested, however decreasing the concentration in chloroform may be useful. Other solvents such as oils (see C8267) or a strong base, such as sodium hydroxide, may also be an option. See the link below to a publication that may be of interest:
