A SERS tag comprising a core comprising at least two aggregated particles of a SERS enhancing material wherein the contact point between the particles defines a crevice; and a reporter molecule having a length sufficiently short to fit into the crevice and a conjugated path length which is as large as possible, provided the overall reporter molecule length is maintained sufficiently short to fit into the crevice.
一种
SERS标记,包括至少两个聚集的
SERS增强材料颗粒组成的核心,其中颗粒之间的接触点定义了一个裂缝;以及一种记者分子,其长度足够短以适应裂缝,并且具有尽可能大的共轭路径长度,前提是整体记者分子长度保持足够短以适应裂缝。
