SYNTHESIS AND CHARACTERIZATION OF SILVER INCORPORATED AMINO-FUNCTIONALIZED MESOPOROUS SILICA NANOPARTICLES

Abstract

This study highlights a facile strategy for synthesizing MSN-based nanostructures using an ionic surfactant CTAB followed by surface modification of MSN through a sylilation process using APTMS ( 3-AminoPropyl TriMethoxy Silicate) . The amine functionalized MSNs were further incorporated with silver nanoparticles prepared by green route. The synthesized samples were further characterized by FTIR and HR-TEM analysis. From the FTIR, it was confirmed that the surfactant CTAB has been completely removed leading to the formation of mesoporous structure. It also confirms the presence of –NH2 group and silver in MSN after functionalization. The mesoporous structure was also confirmed from HR-TEM data. The antibacterial and antifungal studies of the prepared samples were also studied.
