Cancer Smart Bomb

Chemotherapy has always been seen as a way of fighting cancer, but now smart nanotechnology particles have been designed to battle cancer cells. They are actually attracted to the cancer cell by short strands of RNA on the nanoparticles that tells cancer cells apart from others due to what is on their surface. The chemo-loaded nanoparticles then latch onto the signature molecules on the cancer cell that tell it apart from others, and are absorbed into the cancer cell before releasing their load. Tests have been going on with mice to compare the results of chemotherapy to the nanoparticles, and safety trials to treat people with prostate cancer using the nanoparticles may be ready to go underway in two to three years.
