Surface enhanced Raman spectroscopy (SERS) has been widely used for chemical detection. Moreover, the inherent richness of the spectral data has made SERS attractive for use in detecting biological materials, including bacteria. This review discusses methods that have been used to obtain SERS spectra of bacteria. The kinds of SERS substrates employed to obtain SERS spectra are discussed as well as how bacteria interact with silver and gold nanoparticles. The roll of capping agents on Ag/Au NPs in obtaining SERS spectra is examined as well as the interpretation of the spectral data.
表面增强拉曼光谱（SERS）已被广泛用于化学检测。此外，光谱数据的固有丰富性使得 SERS 成为检测生物材料（包括细菌）的一种有吸引力的方法。本综述讨论了用于获得细菌 SERS 光谱的方法。讨论了用于获得 SERS 光谱的 SERS 衬底的种类，以及细菌与银和金纳米粒子的相互作用。还研究了在获得 SERS 光谱时，Ag/Au NPs 上封端剂的作用以及光谱数据的解释。
