Abstract

We introduce a cyanide selective microfluidic platform, in which fluorescent chemodosimeter 1 displayed a selective green fluorescence upon the addition of cyanide. Our system was examined in aqueous solution, and the 'OFF-ON' type emission change can be monitored over 500 nm. In addition, colorimetric change was also observed upon the addition of cyanide. The practical use of the probe was demonstrated by its application to the detection of cyanide in the living cells.
