Abstract
3-Aminopropyltriethoxysilane (APTES) is one of the most important silicon compounds in chemistry for the synthesis of materials. It has extensively been used as a silanization agent for the chemical modification of metal oxide nanoparticle (MONP) surfaces. The introduction of amine (NH2) enhances their dispersibility and anti-bacterial property. The APTES-MONPs have various direct applications in electrochemical sensors, catalysts and Pickering emulsions. In this review article, exemplary APTES modifications of MONPs for unique biomedical, industrial and scientific applications are highlighted. APTES modification provides a linkage for numerous organic, inorganic, or biochemical attachments that are essential to drug delivery, contaminants removal, catalyst immobilization, and medical imaging.
