Abstract

We present a water soluble and fluorescent biotinylated probe derived from a carbocyanine dye. A high efficiency of energy transfer was measured when the dyes were placed on the surface of streptavidin conjugated quantum dots. The system is a model platform for potential application as a FRET-based fluorescent sensor.

摘要

我们提出了一种水溶性和荧光生物素化探针,它源自一种碳菁染料。当染料被放置在链霉亲和素偶联的量子点表面时,测量到了能量转移的高效率。该系统是一种潜在的基于荧光共振能量转移(FRET)的荧光传感器应用的模型平台。
