Time-depended Quenching Behaviors of Multi-dye Systems by Single-Walled Carbon Nanotubes

Ying Tan, Kazuo Umemura

Abstract

A fluorescence quenching phenomenon of fluorophores or dyes could be observed with single-walled carbon nanotubes (SWNTs) suspension. In this study, uranine (Ur) and Rhodamin B (RB), were employed as fluorophores to research time-depended quenching behaviors of multi-fluorophore system by SWNT suspension with single-stranded DNA (SWNT-T30). The effect of “simultaneous quenched” scheme (Ur and RB were quenched at the same time) and “un-simultaneous quenched” scheme (Ur was quenched to equilibrium state, then RB was added; or RB first quenched, then Ur added) to the quenching properties of multi-fluorophore system by SWNT-T30 were compared and researched. The quench equilibrium could be realized in 10 min, for both single and multi-quenching system. Quenching balance and quenching efficiency of each dye basically was not impacted obviously, whether there was another dye existed in the same solution or not. The results or the methodology was important for the future multi-sensor design and application, as it is essential to check the dynamic balance of quenching behavior and confirm that if the quenching performance of target or hunter of sensor (or multi-sensor) was influenced by other constituents.
