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 serves as a spacer, enhancing the spatial freedom of biomolecules during immobilization, which leads to higher specific activity. This compound can establish a more stable, sensitive, and highly biocompatible bioanalytical platform by immobilizing biomolecules onto various solid materials, electrode materials, nanomaterials, and nanocomposites.
