Nanoparticles improve chemotherapy treatment

So they're not improving the drugs and efficiency, as such, but changing up how fast the treatment can be assessed. Okay - got it.

A device developed by chemists at Université de Montréal promises to improve the way a powerful cancer-fighting drug is administered to patients. By using nanoparticles to generate optical effects, this new technology will make it possible to determine almost immediately how much of the drug remains in a patient’s bloodstream, a measurement that currently takes about half an hour. “Using this approach you can get a response in a couple of minutes, depending on the concentration,” says UdeM chemistry professor Jean-François Masson.
