Swedish researchers developed nanorobots that selectively kill cancer cells in mice using a DNA origami "kill switch" activated by the acidic tumor microenvironment.
Researchers at Karolinska Institutet in Sweden have developed nanorobots that kill cancer cells in mice, with a hidden weapon exposed only in the tumor microenvironment, sparing healthy cells. The study, published in the journal Nature Nanotechnology, used DNA origami to create a "kill switch" that activates under the low pH, acidic microenvironment typically found around cancer cells.
