A TEAM of researchers at Karolinska Institutet in Sweden have successfully developed nanorobots that can kill cancer cells in mice. This study, published in Nature Nanotechnology, demonstrates the potential of nanotechnology in effective cancer treatment and research.The innovative nanorobots contain a hidden weapon with a “kill switch” that only activates in the acidic microenvironment of a tumor, specifically targeting and killing cancer cells.
Since cancer cells are usually surrounded by an acidic microenvironment, the weapon activates only when the pH drops to 6.5, targeting and killing cancer cells but not harming healthy cells.A 70 percent reduction in tumor growth was observed when these innovative nanobots were injected into mice with breast cancer tumors, compared to mice that were given an inactive version of the nanorobot.
