Au-covered hollow urchin-like ZnO nanostructures were prepared with controlled size by combining nanosphere lithography (NSL), atomic layer deposition (ALD), electrodeposition, and electron beam (e-beam) evaporation.
Surface enhanced Raman scattering (SERS) technology has attracted increasing attention in histopathologic examination for tumor diagnose due to its high resolution and photo-stability. However, the diagnostic accuracy is inadequate due...
