Surface Enhanced Raman Scattering Based On Nanomaterials As Substrate

总结: Raman scattering is the inelastic scattering of photons, and the device described here aims to provide a substrate for Raman scattering detection. The substrate comprises various nanostructures, and metal nanoparticles are arranged on top of the nanostructures. The arrangement of nanoparticles on a nano-based substrate increases the surface area and may yield higher sensitivity, compared to the use of a conventional substrate. This is due to the fact that the size and dimensionality of nanoscale materials give rise to unique properties associated with surface and quantum effects. The nanostructures may be nanowires, nanorods, nanochains, nanoribbons, nanotubes, nanocables, nanowhiskers, nanobelts, or nanosheets.

技术应用: •Ultrasensitive SERS can be used to detect chemicals, biomaterials and environmental substances
•The technology is relevant to biochips and lab-on-a-chip applications for characterizing specific DNA fragments without using fluorescent or radioactive labels
