South Korean researchers have found a new approach to cancer treatment, they claim - through a nanorobot. According to a Reuters report, non-toxic salmonella bacteria are genetically modified to create a nanorobot filled with capsules containing drugs. The BacteriaBot (as it has been nicknamed) can identify the cancer and attack it without damaging healthy cells. At the moment the nanorobot only works on mass tumors (as typical of cancers of the breast and colon), but the researchers are hoping to expand the technology further.
If successful, the BacteriaBot could replace chemotherapy and its often-adverse side-effects. So far, the technology has been patented in the US, Japan and in Europe, but has not been approved for human testing yet.
