3-Aminopropyltriethoxysilane (APTES) functions as a strong adhesive for immobilizing biomolecules, such as antibodies and enzymes, onto silicon and its derivatives like silicon nitride (Si3N4). It also acts as a spacer, allowing biomolecules more spatial freedom during immobilization, which results in higher specific activity. APTES can establish a more stable, sensitive, and highly biocompatible bioanalytical platform by immobilizing biomolecules onto various solid materials, electrode materials, nanomaterials, and nanocomposites.
- Acts as a strong glue for immobilizing biomolecules (antibodies, enzymes) onto silicon and silicon derivatives.
- Functions as a spacer, increasing spatial freedom for biomolecules during immobilization, leading to higher specific activity.
- Contributes to the formation of a more stable, sensitive, and highly biocompatible bioanalytical platform.
