摘要: We report a simple and general strategy for selectively exposing functionalizing the sharp corners of concave nanocubes, which are SERS hot spots such structures. This takes advantage unique shape cubes by coating particles with silica then etching it away to expose only corner regions, while maintaining in faces. These regions can be modified improved enhancement signal response SERS.
