A Novel Carbon Sensor for Spotting Dangerous Food Chemicals

Scientists have come up with a new way to detect harmful substances like chloramphenicol (CP) and furazolidone (FZ) in food, using a special sensor made from carbon paste. This sensor is modified with a chemical called Fmoc-Pro-Phe-OMe, which scientists have carefully characterized using advanced tools like mass spectroscopy and FTIR. The sensor works by measuring changes in electrical signals when CP and FZ are present in a solution, helping to spot these dangerous chemicals.

Tests showed that this sensor is really sensitive and can pick up tiny amounts of CP and FZ. In fact, it can detect as little as 0. 014 microM of CP and 0. 015 microM of FZ. What's more, the sensor is reliable and consistent, showing excellent repeatability and stability. It can even handle real-world tests, successfully detecting CP and FZ in milk and honey samples. Scientists also studied how the sensor works under different conditions to make sure it performs well. They found that the sensor's ability to detect CP and FZ improves when the surface area of the electrode is larger. The more surface area, the better the sensor can catch the chemicals. Overall, this new carbon paste sensor offers a promising way to keep our food safe by detecting harmful chemicals.
