Bimetallic alloy Ag@Au nanorings with hollow dual-rims focus near-field on circular intra-nanogaps
{{output}}
Here, we report a highly sensitive and reliable surface enhanced Raman scattering (SERS)-based immunoassay using bimetallic alloy Ag@Au hollow dual-rim nanorings (DRNs) where two hollow nanorings with different diameters are concentrically overlapped and conne... ...
