A new protein micelle can deliver cancer drugs and while researchers track it with MRI to make sure it's working as intended.

Drug delivery that's more like "painting by numbers," rather than paintball, would allow precise delivery of a certain amount of drugs to an exact location.

The structure of a virus that infects bacteria in hot springs could improve both DNA analysis and drug delivery.

An inexpensive, simple method could improve drug delivery, chemical sensors, and fluid pumps by controlling nanoparticles in liquid.

The way bacteria battle against other strains could lead to better, "smarter" antibiotics that only kill the bugs that are making us sick.

The new method uses a red glow to screen hundreds of nanoparticles at once to find which could best deliver drugs into living cells.
