Bullet-like nanoparticles heat and destroy cancer cells from the inside
  • Gold nanoparticles were used in a lab to destroy cells of mesothelioma - a “hard-to-treat” cancer caused by exposure to asbestos.
  • The nanoparticles are created by putting gold on silver nanoparticles, causing the silver to dissolve, and leaving a hollowed out golden tube.
  • When the gold tubes were absorbed by the cancer cells, they were heated up with laser light, killing the cancer cell.
  • This could potentially be used in the future to cause localized cancer-cell killing, researchers are working to improve the method.
  • One approach they’re exploring is to add medicine to the tubes to “supercharge their cancer-killing abilities”.
