Researchers at Nanjing University in China have developed a portable device that can detect additives, toxins, and sweetness in alcoholic beverages using biological nanopore technology. This 'artificial tongue' operates similarly to a COVID test, requiring just a drop of the drink for analysis. The device utilizes a modified organism with a nanopore to create a unique electrical signature for each molecule passing through, which is then identified by an artificial intelligence algorithm. While not yet able to detect date rape drugs or methanol contamination, this technology has the potential to significantly improve the safety and authenticity of alcoholic beverages.
Drinks manufacturers and consumers may soon have a small, portable kit, not much bigger than a covid test, to check the quality and safety of alcoholic beverages.
The device is being described as an “artificial tongue” because it can detect additives, toxins and the sweetness of the drink with just a few drops.at Nanjing University in China says that while this first generation of the new technology can’t yet test for date rape drugs in spiked drinks or detect methanol contamination, which
Current methods for analysing alcoholic drinks, such as liquid chromatography, involve expensive and cumbersome laboratory equipment, requiring expert technicians to operate and analyse samples. The artificial tongue relies on biological nanopore technology. This uses a modified organism such as a bacterium with a small hole or pore, just a few nanometres in diameter, in its cell membrane. By charging the membrane with electricity, small molecules of the substance being tested can be pulled into and through the pore.As these molecules pass through the nanopore they create a unique electrical signature, which can be analysed to identify the chemicals present in the sample.
The nanopore detector only needs a source of electricity to operate, he says. “This nanopore sensing assay can be carried out at home, in the office or by the roadside as well, as simple as a covid test,” Huang says. “The only thing you need to do is to add a drop of alcoholic beverage to the sensor and wait for the result. The machine learning algorithm will do the rest of the job for you.”
