NIR fluorescent biotinylated cyanine dye: Optical properties and combination with quantum dots as a potential sensing device

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. © 2013 The Royal Society of Chemistry and Owner Societies.
