  Isotopically substituted rhodamine dyes provide ideal probes for the study of single-molecule surface enhanced Raman scattering (SM-SERS) events through multiple-analyte techniques. Isotopic editing should, in principle, provide probes that have identical chemical properties (and surface chemistries); while exhibiting at the same time distinct Raman features which enable us to identify single-molecule SERS events. We present here a specific example of two-analyte SM-SERS based on the isotopic substitution of a methyl ester rhodamine dye. The dyes are carefully characterized (in both standard and SERS conditions) to confirm experimentally their similar chemical properties. We then demonstrate their utility for bi-analyte SERS (BiASERS) experiments and, as an example, highlight the transition from a single, to a few, to many molecules in the statistics of SM-SERS signals.

  同位素替代的罗丹明染料为通过多分析物技术研究单分子表面增强拉曼散射（SM-SERS）事件提供了理想的探针。从理论上讲，同位素编辑应该提供具有相同化学性质（和表面化学）的探针，同时展现出不同的拉曼特征，使我们能够识别单分子SERS事件。我们在这里提供一个基于甲基酯罗丹明染料同位素替代的双分析物SM-SERS具体示例。这些染料在标准条件和SERS条件下都经过仔细表征，以实验上确认它们相似的化学性质。然后，我们展示了它们在双分析物SERS（BiASERS）实验中的实用性，并以此为例突出单个分子、少量分子到大量分子在SM-SERS信号统计中的过渡。
