    Curcumin a Colorimetric and Fluorimetric Cyanide Probe in Aqueous System and Living Cells by Hijji, Yousef

    Published 2019
    “…Cyanide causes a dramatic color change of the curcumin solution (acetonitrile : water 90 : 10) from bright yellow to dark orange. It causes dramatic spectral changes in the UV-vis spectrum of curcumin by the decrease in the absorption band intensity at 421 nm and a concomitant appearance of a strong band at 520 nm. …”
