Surface-enhanced Raman scattering substrate and Raman detecting system having the same

摘要

A surface-enhanced Raman scattering substrate includes a carbon nanotube film structure and a plurality of metallic particles disposed on the carbon nanotube film structure. The carbon nanotube film structure includes a number of carbon nanotubes joined by van der Waals attractive force therebetween. The carbon nanotube film structure is a free-standing structure.
