An ingestible chip relies on E. coli to offer a non-invasive way to detect bleeding in the stomach.
To create the chip, the team at MIT placed genetically modified E. coli bacteria within the semi-permeable membrane of an ingestible 1.5-inch cylinder. The bacteria will generate light when they come in contact with heme—a component of blood—which is detected by phototransistors also placed in the cylinder. That data is transmitted to a paired smartphone, offering a real-time warning of gastrointestinal bleeding.
