Scientists from Turkey have designed an implantable biosensor using genetically engineered E. coli for molecular-level monitoring within the body that runs on its own, wirelessly, with no external batteries required.

The researchers reprogrammed E. coli to express cytochrome c maturation (Ccm) proteins, creating a synthetic genetic circuit that switches on when the bacteria detect a specific target molecule………….Extending this approach to diverse bioengineered cell types and molecular targets could revolutionize how we monitor disease progression in real time, eliminating the need for repeated biopsies or invasive sampling.

I can see the good here when it comes to early alerts for diseases cancer, but worry there will be people who'll want to use it for ways to track and monitor things. Mandatory permanent drug screen at workplaces, for example.
