Research Abstract

In this study, we aimed to develop highly-sensitive labeling agents by incorporating fluorophores into DNA. We developed artificial base pairs by incorporating cyclohexane derivatives between a fluorophore and nucleobases. As a result, quantum yields of fluorophores such as pyrene and perylenediimide were drastically enhanced. In addition, we demonstrated that the quantum yield of FITC was also improved by incorporating cyclohexane derivatives.
