Now your smartphone will identify germs in food

In the coming days, you will also be able to find out whether your food is contaminated or not, that too with the help of your Smart Phone. Researchers at Purdue University have developed a new device that identifies the presence of harmful bacteria in food samples.
Our goal is to create a technology that allows an easy, expedient and efficient process to detect the causes of food-borne diseases in a low-cost effective manner, said Uivan Bay, a senior research scientist for mechanical engineering at Purdue.
The new device uses a bioluminescence-based essay, which can be tested onsite of E. coli bacteria by pairing it with a Smart Phone and a laptop.
With a silicon photomultiplier device that uses low light with a bioluminescent asset, users can detect the presence of bacteria in food samples.
