ULSAN, South Korea — South Korean researchers from the Ulsan Institute of Science and Technology (UNIST) have developed a cutting-edge method to treat cancer using tiny, specialized devices called “nanodrones.” These revolutionary nanodrones are engineered to specifically target and destroy cancer cells. To understand this, we first need to know about Natural Killer (NK) cells. NK cells are a type of white blood cell that play a vital role in defending our body against cancer. Scientists have long aimed to use these cells in cancer treatment. The UNIST team’s breakthrough, named NKeNDs (NK cell-engaging nanodrones), utilizes a kind of nanoparticle...
