Silane-PEG-DBCO

Price range: $360.00 through $1,800.00

Silane-PEG-DBCO is a heterobifunctional PEG derivative containing a silane group and a dibenzocyclooctyne (DBCO) group at opposite ends of the polyethylene glycol chain. The silane moiety enables covalent attachment to hydroxyl-containing surfaces such as glass, silica, quartz, and metal oxides, while the DBCO group readily reacts with azides through copper-free click chemistry (SPAAC). Silane-PEG-DBCO is widely used for surface functionalization, nanoparticle modification, biosensor fabrication, and bioconjugation applications.

Silane-PEG-DBCO structure

Description

General Description

Silane-PEG-DBCO combines surface immobilization capability with bioorthogonal click chemistry functionality in a single molecule. The silane group forms stable siloxane bonds with hydroxylated inorganic surfaces, allowing durable PEG coatings on glass, silica nanoparticles, silicon wafers, and metal oxide materials.

The DBCO group reacts efficiently with azide-containing molecules without requiring copper catalysts, making it ideal for biological applications where copper toxicity is undesirable. The PEG spacer improves hydrophilicity, flexibility, and biocompatibility while reducing nonspecific adsorption.
