A gold(III) ion-selective fluorescent probe and its application to bioimagings
Organic letters, Volume 11, Issue 24, 2009, Pages 5610-5613.
A highly selective and sensitive fluorescent chemosensor for Au(3+) has been reported. The system utilizes an irreversible Au(3+)-promoted cyclization reaction of a rhodamine amide tethered with an alkyne. The probe can sense Au(3+) ions selectively over other biologically relevant metal ions, and approximately 50 nM of Au(3+) could be re...More
