Cyanide anion is widely used in industry but has high toxicity as waste. Plant seeds also contain cyanide, which is often consumed by humans. Many studies have been conducted to determine cyanide, and optical sensors that show colorimetric and fluorimetric changes have gained significant interest due to their simplicity, affordability, and rapid response.
Cyanide anion has wide use in industrial areas; however, it has a high toxic effect on the environment as waste. Moreover, plant seeds contain cyanide that is often consumed by human beings. Therefore, many studies are carried out to determine cyanide. Especially, optical sensors showing colorimetric and fluorimetric changes have been of considerable interest due to their easy, cheap, and fast responses. This review discusses recent developments in the colorimetric and fluorimetric detection of cyanide by nucleophilic addition to different types of receptors via the chemodosimeter approach. The sensitivity and selectivity of the sensors have been reviewed for changes in absorption and fluorescence, naked-eye detection, real sample application, and detection limits when interacting with cyanide.
