A simple and efficient SERS substrate using conventional methods is achieved through the incorporation of chemical vapour deposited graphene. The study covers the growth of CVD graphene film starting from substrate pre-treatment, various analyses of the film and finally the application in SERS....
Enhanced absorbance in a hybrid graphene-metamaterial structure on a reflective substrate was proposed in ref. 26. In addition to its intrinsic 2D geometrical properties, graphene affords with a extensive graphene control of sheet, the its conductivity σdue gate voltage can tune to its gate-...
We have demonstrated that an SERS assay based on the PEGylated trilayered substrate, in combination with magnetic separation, allows for sensitive, multiplexed "signal-off" detection of DNA sequences of bacterial pathogens. 展开 DOI: 10.1039/C5NR02164B 被引量: 3 ...
Lin et al. studied DNA hybridization by utilizing self-assembly of Ag NPs and SERS substrate based on Ag NPs and graphene (Ag NPs–graphene) nanocomposites. AgNPs are modified with non-fluorescent 4-mercaptobenzoic acid (4-MBA) which is a very efficient Raman probe for DNA...

Methods, devices, systems and/or articles related to techniques for forming a graphene film on a substrate, and the resulting graphene layers and graphenated substrates are generally disclosed. Some example techniques may be embodied as methods or processes for forming graphene. Some other example ...
This new perspective allows control of SERS in the case of graphene on plasmonic metamaterials or nanostructures and potentially paves the way towards an advanced SERS substrate that could lead to the detection of single molecules attached to graphene in future biochemical sensing devices.Advanced ...
Direct exposure of the silver-based SERS substrate to non-ideal environment may also cause degrada- tion of SERS activity, due to the chemically instability of Ag. But, we found that the graphene-shield SERS substrate could be stable in those environments. Figure 5a shows the CV spectra ...
the sheet structure helped it withstand corrosion. Drying times are shortened by silicone modification, which also increases coating-substrate adhesion and hardness [Du et al.2021]. Interest in creating innovative nanostructured materials with minimal VOC emissions has increased. Vegetable oil-based alkyds...
