Using bugs in the gut to detect blood

Bacteria are environmentally resilient and can be engineered to sense various biomolecules. Mimee et al. combined biosensor bacteria with a miniaturized wireless readout capsule to produce a minimally invasive device capable of in vivo biosensing in harsh, difficult-to-access environments (see the Perspective by Gibson and Burgell). The device successfully measured gastrointestinal bleeding in pigs.
