摘要

A novel metal nanoparticlesmesoporous silicas with high surface area ( 300 m2g-I ), large pore size (> 5.0 nm) and high metal nanoparticles content (~ 10 wt.%) have been prepared and used as surface enhanced matrix for bacteria charectization under Raman scattering analysis. The prepared nanoparticles@mesoporous silicas present great adhesion ability to direct contact with microorganism, i.e. S. aureus. The characterized peak at 1523 cm-I can be gradually enhanced from original 200 counts to 1000 and 4000 counts when Au content increased to 6% and 4%, respectively.
