- A research team at the Central University of Kerala has developed a highly sensitive and selective cyanide sensor.
- This breakthrough material detects toxic cyanide at low concentrations, promising enhanced safety in drinking water and food products.
- The research has been published in the Journal of Photochemistry and Photobiology A: Chemistry.
- The novel sensor changes colour from yellow to colourless upon detecting cyanide, providing a straightforward visual cue.
- It selectively identifies cyanide without interference from other ions, ensuring accuracy in various testing environments.
| Cyanide • It is a potent toxin found in various plants, fruits, and microorganisms. • It is regulated by the WHO, which limits its presence in potable water to below 0.19 mg/L due to its lethal effects on humans and aquatic life. • Exposure can occur through the consumption of cyanide-rich foods like cassava, apple and apricot seeds, sprouting potatoes, and almonds, posing significant risks, especially in regions where these foods are staples. |
