In this paper we report that the location of the strongest electric filed of quasi-3D gold plasmonic nanostructure arrays can be conveniently tailored by simply varying the diameter of the nanoholes in the film while maintaining the same spacing, depth and material properties. As a result, optimal SERS sensitivity for detecting different size analytes, such as small molecules and intact microorganisms like bacteria, can be achieved.
