Fully Autonomous DNA Nanorobots Target and Starve Tumors in Mice

A team of scientists in the U.S. and China has created programmable DNA origami nanorobots that can seek out and shrink tumors by blocking their blood supply. Tests in mice carrying breast, melanoma, ovarian, and lung tumors showed how the DNA nanorobots homed in on cancer-feeding blood vessels and induced the formation of clots, which effectively shut off the tumors' lifeline of oxygen and nutrients. The results included stunted tumor growth, shrinkage of existing tumors and metastasis, and inh
