NASA invention attacks cancer cells inside out like a hand grenade

Thinking aloud:

Not exactly sure how ferrofluid can be classified as a form of ‘targeted therapy’ (targeted therapy is drug therapy that targets cancer cells only and leaves healthy cells alone). Targeted therapy usually targets the proteins or nucleic acids dotted on the cell exterior (cell surface membrane of cancer cells). Can’t see how ferrofluid acheives that unless coupled with a protein. Another option can be the permeability of the cell exterior (cancer cell surface membrane). But cancer cells have low membrane permeability so ferrofluid can’t just easily slide into them – unless it can interact with lipids on the surface of the cell… Hmmm….would love to discuss this!
