Iranian Researchers Produce Optical Sensor to Detect Cyanide in Fruit Seeds

“Over the past few decades, many sensors have been used for this purpose, and scientists have sought to make sensors with high sensitivity and optimal selectivity to detect cyanide rate, both in aquatic environments and in foods,” Ali Akbar Tarlani, a professor of CCERCI, who was the executive director of the project to produce optical sensor said according to a report by CCERCI public relations department.

“In this project, a new composite based on graphene quantum dots (GQDs) in a composition with a porous metal-organic GQDs@ZIF-11 composite was designed and identified to selectively detect cyanide ions among 19 other ions in the presence of photoluminescence, which is a big advantage,” he added.

According to him, another advantage of the optical sensor is that it can detect nanomolar cyanide ions.

The professor said that the cyanide in apple and bitter almond seeds was measured by the new optical sensor and it was found that each gram of the seeds contained 2.4 and 2.5 milligrams of cyanide.

According to the report, findings of the research was published in the form of an article in Microchemical Journal (2023).
