<pre>A special device for the smartphone will find any bacteria in the food

How to evaluate the purchased products for contamination with harmful bacteria? Already in the near future for this will be an inexpensive device for a smartphone, which will give its ability to detect these bacteria. The gadget is developed by scientists from the University of Amherst in Massachusetts.

The research team is headed by food specialist Dr. Lili Hee. Scientists have already developed a chip containing 3-MBPA acid molecules, which, like a magnet, attract bacteria to themselves.

The chip is immersed in the product under investigation, after which it is washed with a concentrated buffering liquid that flushes the sugar, fats and proteins contained in the product, leaving all the bacteria in place.

The chip is then placed in a simple light microscope designed to work with smartphones. A special application counts the number of bacteria on the chip. The device is very sensitive and will be able to detect even a small number of bacterial cells, for example, 100 units per 1 milliliter of solution.

This result has already been confirmed in a two-hour experiment. For comparison, the standard method of research takes 2 days. There are other methods for rapid detection of bacteria, but they are not as sensitive and reliable as this chip.

Scientists hope that the technology developed by them will become available not only for nutrition workers, but also for specialists working in disaster zones that need to be sure of food and water safety.
