Gold-plated nanoparticles find and destroy cancer cells

Scientists have merged tiny gold and iron oxide particles, then added antibodies to steer them through the bloodstream towards colorectal cancer cells.

The gold-plated alloys then kill the targeted cancer cells with absorbed infrared heat.

As cancer cells only need to be heated up a few degrees to die, gold nanoparticles (which allows low energy heat to be used efficiently) can target them better without causing heat damage to healthy tissues.

This results in a threefold increase in killing cancer cells and a substantial tumor reduction within 30 days.
