We reported on a study upon a Surface-enhanced Raman Scattering (SERS) substrate produced from a large area multi-walled carbon nanotube (MWCNT) films decorated with Au nanoparticles. The morphology and spectrum of the MWCNTs/Au composite structure was characterized with scanning electron microscopy and spectrophotometer. The SERS signals of Rhodamine 6G (R6G) absorbed on the substrate were improved, which could contribute to the enlarged surface area for adsorption of molecules and Localized Plasmon Resonance Effect. The results indicated that it is potential to produce sensitive SERS substrates via further fine-tuning of size, shape of the nanostructure.

Enhanced Raman Scattering

The development of new surface-enhanced Raman scattering (SERS) substrates is primarily motivated by designing synthetic substrates to obtain the significant signal enhancement. In this paper, a large-scale carnation-shaped Ag meso-flowers monolayer with sufficient “hot spots” has been synthesized on copper foil without using any capping agent. In dimethyl sulfoxide, AgNO3 is reduced by Cu for 60 min at 35 °C through the galvanic displacement reaction, and carnation-shaped Ag meso-flowers with good crystallinity and high purity are obtained. The as-fabricated carnation-shaped Ag meso-flowers monolayer is used as novel SERS substrates. Non-fluorescent 4-mercaptobenzoic acid is selected as the probe molecule to test the SERS activity, uniformity and enhancement factors (EF) of the monolayer. Experimental results show that the EF of the carnation-shaped Ag meso-flowers monolayer is up to 7.06×108 and the limit of detection is 10-11 M. Meanwhile, the biocompatibility of the carnation-shaped silver meso-flowers monolayer is tested for red blood cells detection. SERS measurements demonstrate that the carnation-shaped silver meso-flowers monolayer has good activity, uniformity and biocompatibility, and can be used as an outstanding SERS substrate, which has a broad application prospect in numerous chemical and biochemical sensing applications.
