可以看看这一篇,发表在Anal. Chem上面,有一定的可靠性。
Zhong LB, Yin J, Zheng YM, Liu Q, Cheng XX, Luo FH: Self-Assembly of Au Nanoparticles on PMMA Template as Flexible, Transparent, and Highly Active SERS Substrates. Anal Chem 2014, 86:6262-6267.
Abstract:We report a simple and rapid method for fabricating a surface-enhanced Raman scattering (SERS) substrate, which offers good flexibility, excellent optical transparency, and high SERS activity. Specifically, the SERS substrate (AuNPs/PMMA film) was obtained through self-assembly of gold nanoparticles (AuNPs) on newborn poly(methyl methacrylate) (PMMA) template. The UV-vis spectroscopy analysis and scanning electron microscopy observation revealed that the gold nanoparticles were closely assembled on the flexible and transparent PMMA template. The fabricated AuNPs/PMMA film SERS substrate allowed detection of model molecule, malachite green isothiocyanate, at a concentration as low as 0.1 nM, and exhibited good reproducibility in the SERS measurement. The Raman enhancement factor (EF) of the AuNPs/PMMA film was found to be as high as (2.4 +/- 0.3) x 107. In addition, measure of residual malachite green on fish surface was carried out, and the result indicated that the AuNPs/PMMA film had great potential in the in situ ultrasensitive detection of analyte on irregular objects.
