| Research Abstract |
We have found a way to fabricate probes for nano-Raman imaging with sufficiently-high quality, in which AFM cantilevers were pre-heated in air at 900 deg. C for 10 h to form oxide layer and dull edge facilitating Ag nanoparticle growth on top of the lever with high reproducibility. We also succeeded to immobilize single AgNP using an AFM mode. Both of these preparation methods enabled us to obtainprominent TERS spectra for PATP on Ag island films.
