Synthetic structures made of DNA could one day be used to deliver cancer drugs directly to tumor cells, and customized proteins could be designed to specifically attack a certain kind of virus. Although researchers have already made such structures out of DNA or protein alone, a Caltech team recently created- for the first time -a synthetic structure made of both protein and DNA. Combining the two molecule types into one biomaterial opens the door to numerous applications.
