Synthetic Biology Circuits for Programmable Cell-Based Biosensors
Quick fact
In 2021, researchers engineered bacteria that can detect and report the presence of tumor DNA in the gut, offering a potential non-invasive diagnostic for colorectal cancer.
Why this is interesting
What if a bacterium could be programmed to turn red when it detects a hidden chemical, or glow when it finds a cancer marker in your blood? That's not science fiction—it's the promise of synthetic biology circuits.
