N2 - Well-ordered acute-angled Au nanorod (NR) arrays were fabricated using a focused ion beam (FIB) (fibAu-NR). The angle between the NRs and the substrate was tilted at 30-90°. A fibAu-NR with an angle of less than 90° significantly increased the effect of surface-enhanced Raman scattering, which was evaluated using low-concentration rose bengal (<10-5M) as the molecular test probe. The results show that an angled NR surface produces a strong local electromagnetic effect owing to a large number of Raman active sites. In addition, an optimized fibAu-NR was found to distinguish cyanuric acid in milk solution with good reproducibility.
