银片和镀银的金纳米棒的尺寸为20-100 nm(具有10-20 nm的短轴；见图)，已被确定为表面增强拉曼光谱(SERS)衬底的极佳候选者。盐诱导的颗粒聚集是获得高灵敏度的关键。
Silver platelets and silver-coated gold nanorods 20-100 nm in size (with a 10-20 nm short axis; see figure) have been identified as excellent candidates for surface-enhanced Raman spectroscopy (SERS) substrates. Salt-induced particle aggregation is essential in obtaining high sensitivity.
