摘要

We experimentally observe and isolate chemical-enhancement effects in the Raman spectra of nucleotides on gold nanorod surfaces. We compare the enhanced spectra with similar enhancements observed on silver surfaces, and demonstrate their potential for DNA composition analysis. (C) 2019 The Author(s)
