Ultrasensitive Surface-enhanced Raman Scattering Detection with Nanoparticle-functionalized Amino Silica Monolith

doi:10.7503/cjcu20130623

Abstract

Abstract:

A novel type of amino silica monolith was developed by the sol-gel reaction combined with a supramolecular template-based approach in a simple and rapid manner. By the co-condensation of tetraethoxysilane(TEOS) and (3-aminopropyl)triethoxysilane(APTES) in the presence of cetyltrimethylammonium bromide(CTMAB), the silica-based hybrid material with active amino groups bonded to the silicon atoms was obtained. After injecting a gold nanoparticles(AuNPs) colloid into the monolith, a very dense homogeneous coverage of AuNPs was obtained and all AuNPs were assembled directly on the monolith surface. The nanoparticle-functionalized monolith was then used for a surface-enhanced Raman scattering(SERS) substrate and it provided high enhancement activity and reproducibility. The minimum detectable concentration of this SERS column is 10^-9 mol/L for PATP and 10^-11 mol/L for crystal violet(CV). This nanoparticle-functionalized amino silica monolith will be powerful SERS substrate for ultrasensitive detection of toxins and contaminants in the field.
