Özet
Cyanide ion (CN−) is widely used in many industrial processes; however, it causes several diseases in humans. Therefore, rapid and accurate detection of CN− is very important and urgent. In this study, a CN− sensor (MH-2) which was capable of detecting CN− ions in living cell was developed. MH-2 gives a rapid color change, absorbance and fluorescence response to CN− in the presence of the anions tested in the working system. The binding ratio between the sensor and CN− was demonstrated by some spectrophotometric methods and the sensing mechanism was investigated by NMR titration experiments, suggesting that MH-2 gives response to CN− via the nucleophilic addition reaction. The fluorescence detection limit and the absorbance detection limit were calculated as 0.056 μM and 0.11 μM, respectively. Both of these detection limits are below the tolerable limit recommended by WHO for CN− in the drinking water (1.9 μM). MH-2 was also applied to living cells for bio-imaging and the results showed that the sensor penetrates the cells and can detect cyanide ions in living cells.
