Researchers have tricked cancer cells into eating balls full of poison, killing the cells and effectively treating breast cancer in a bunch of mice, says a new report in the journal Nature, published March 14. These miracle balls are called nanoparticles, and they could be the key to finding, diagnosing and treating a number of illnesses in the future — once we figure out how to make them do their jobs.
Think of nanoparticles as little delivery trucks. They can be loaded with almost anything from a medical lab — medicine, fluorescent agents or, in this case, poison. But these delivery trucks are tiny.
Actually, tiny isn’t the right word. The screws on your glasses are tiny. The pebbles that get stuck in your shoes are tiny. A grain of sand (the poster child of tiny) is still 5,000 times bigger than the largest nanoparticle.
