title: 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.
