Scientists have been toying for years with creating tiny implants and nanorobots that could carry drugs to certain diseased cells. It is about as targeted as therapy can get, but at this point it’s all a bit futuristic.
Within the confines of petri dishes, researchers are still tinkering. A new study is the first to demonstrate that a nanorobot, which the researchers are calling a DNA nanocage, can both encapsulate and release a biomolecule without degrading the cage itself — and at a size small enough to keep the drugs trapped until they reach the end target.
