Layer-by-layer assembly of Ag nanowires into 3D woodpile-like structures to achieve high density "hot spots" for surface-enhanced Raman scattering.Miaosi Chen, In Yee Phang, Mian Rong Lee, Joel K W Yang, Xing Yi LingLangmuir : the ACS journal of surfaces and…2013The surface-enhanced Raman scattering (SERS) "hot spots" are highly localized regions of enhanced electromagnetic field within a SERS substrate that dominate the overall SERS intensity. This results… (More)
