UV-vis spectroscopy measurements of the colloidal solutions were carried out on a Hewlett-Packard 8542 A diode array spectrophotometer operated at 2 nm resolution while measurements on the thiolfunctionalized MCM 41 powder with and without entrapped colloidal nanoparticles were performed in the reflection mode on a Shimadzu UV-2101 PC instrument using barium sulfate as a standard for background correction.
