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.
Applications
- Surface modification of glass and silica materials
- Biosensor and biochip fabrication
