Research Abstract

Mesoporous silica membranes were prepared by incorporating Au nanoparticle. The meso-structures of the membrane were changed by cubic to lamella or hexagonal structures by changing the Au particle amounts. This means the meso-structures can be controlled by the particle amounts. The Plasmon resonances of the mesoporous silica membranes were changed by the change of ligands. This indicates the membrane with Au nanoparticle prepared in this work can be used as membrane sensor.
