Glowing Nanotubes Can Show When Meat Has Spoiled

  • 23 Nov 09:38

Researchers from China have shown it is possible to detect the deterioration of meat by using flurorescent nanotubes. Reporting in the journalACS Sensorsfrom the American Chemical Society, the scientists showed that the highly fluorescent, hollow nanotubes grow dim when they react with compounds given off by meat as it decomposes. The scientists were looking for a new method to test meat, as current methods, despite high sensitivity,require bulky, slow equipment, which prevents real-time analysis. Some newer methods designed to speed up the testing process have fallen short in sensitivity. Yanke Che and colleagues wanted to develop one simple test that could deliver. Read more...
