Maria Temming – April 17, 2018

Summary: This article discusses a flexible film coated in molecules that glow when they come into contact with E. coli, and the presence of molecules secreted by E. coli which allows for the material to detect food contamination without being in direct contact with bacterial cells.

Critical Analysis/Connections: This article does an excellent job of providing a lot of information about the technology to detect E.coli and also how many individuals are killed due to foodborne illnesses. I personally would love to see this technology in the upcoming future in all packaged food. The only downside is having access to an ultraviolet lamp, but they are easily purchasable at the store and online. The article also mentioned a convenient smartphone fluorescent light attachment which could be used. In class, we discussed proper hygiene and contamination of food products. We also have discussed about how dangerous E.coli can be. This invention is a groundbreaking achievement that will save lives in years to come.

Questions: Could this be used to detect other bacteria? How much does it cost to manufacture the film?
