Ratiometric and colorimetric near-infrared sensors for multi-channel detection of cyanide ion and their application to measure β-glucosidase

A near-infrared sensor for cyanide ion (CN(−)) was developed via internal charge transfer (ICT). This sensor can selectively detect CN(−) either through dual-ratiometric fluorescence (logarithm of I(414)/I(564) and I(803)/I(564)) or under various absorption (356 and 440 nm) and emission (414, 564 an...

description A near-infrared sensor for cyanide ion (CN(−)) was developed via internal charge transfer (ICT). This sensor can selectively detect CN(−) either through dual-ratiometric fluorescence (logarithm of I(414)/I(564) and I(803)/I(564)) or under various absorption (356 and 440 nm) and emission (414, 564 and 803 nm) channels. Especially, the proposed method can be employed to measure β-glucosidase by detecting CN(−) traces in commercial amygdalin samples.
