tumor paint
The tumor paint is created by utilizing a protein derived from the paralyzing venom of an Israeli deathstalker scorpion. The re-engineered protein, which binds to cancer cells, is then joined with a fluorescent molecule flashlight that has been used safely in human surgeries for decades. The scorpion toxin finds the cancer cells and drags the flashlight into them and makes them glow brilliantly, Olson said at the convention.
