| Research Abstract |
We have investigated to realize nano-Raman imaging on:
(1) flocculation method to fabricate closely adjacent Ag and Au nanoparticles by controlling the interaction with target molecules such as dye, DNA bases and thiols, which provided single molecule sensitivity using gap mode plasmons,(2) fabrication method of TERS probes using pre-heating of cantilever and AFM mode, which provided pronounced TERS signal for PATP on Ag island films. Conclusively, our projectproceeded quite efficiently towards nano-Rama imaging.
