摘要: We have fabricated bimodal porous gold skeletons by double-templating routes using poly(styrene) colloidal opals as templates. The show a pore-size distribution, with small pores within spheres and large between spheres. templated were applied in Raman scattering experiments to study sensing efficiency for probe molecules. found that the showed obvious enhancement of signals versus unimodal which only has interstitial several hundred nanometers.
