In this study, highly uniform 3D Al nanoneedle arrays (AlNNAs) decorated with Ag nanopines are synthesized by anodization of Al foil with prior nanoimprinting and subsequent electrodeposition method, demonstrating remarkable surface-enhanced Raman scattering (SERS) property. The AlNNAs possess a hig...
