氧化石墨烯的光致发光在 Cy3.5-氧化石墨烯的荧光共振能量转移对中充当受体而非供体。

Abstract

We have systematically studied the fluorescence resonance energy transfer (FRET) efficiency between the photoluminescent graphene oxide (GO) and Cy3.5 dye by controlling the donor-acceptor distance with a double stranded DNA and demonstrated that the GO serves as an acceptor rather than a donor in this FRET system.

摘要

我们通过控制双链 DNA 来改变供体-受体距离，系统地研究了发磷光的氧化石墨烯 (GO) 和 Cy3.5 染料之间的荧光共振能量转移 (FRET) 效率，并证明在该 FRET 体系中 GO 是受体而不是供体。
