Coming up with potent anti-cancer drugs is one thing, delivering them to the site of a tumor inside the body is very much another. With a complicated organism guarded by a highly evolved immune system to navigate, getting these particles to there target in one piece is a challenging task, and one that scientists are continuing to tackle from all angles. A promising new approach developed at Virginia Tech leans on the penetrative properties of a salmonella infection, which they’ve found can be used as a vehicle to smuggle cancer-fighting nanoparticles into a tumor in a huge abundance.

According to Goldman Sachs Research, this contributes to a $100 billion market opportunity between 2016 and 2020.
