FRET-based sensor for imaging chromium(III) in living cells

摘要

On the basis of fluorescent resonance energy transfer from 1,8-naphthalimide to rhodamine, a fluorophore dyad (FD8) containing rhodamine and a naphthalimide moiety was synthesized as a Cr~(3+)-selective fluorescent probe for monitoring Cr~(3+) in living cells with ratiometric fluorescent methods.
