Key points from article :
Most current antibiotics wipe out all bacteria - good and bad.
French startup Eligo Bioscience is creating genetically engineered biological nanobots.
Made of synthesized DNA and protein they could specifically target resistant bacteria.
Nanobots would be inactive until they made their way to the gut.
Use CRISPR gene editing enzyme to scan bacterial DNA and identify their target.
Could be used as a prophylactic drug.
More testing needed before trying in humans by 2020.
