The nanoparticle Zhang created is already being referred to as something of a “swiss army knife” in the area of cancer treatment. That’s not to say it’s dull and rusty because I you didn’t take care of it when I was you were out camping, but rather that it has a whole bunch of useful applications. The nanoparticle is delivered to tumors via the drug salinomycin where it kills cancer cells and deposits gold and iron-oxide materials to help with MRI imaging.
