NewsResearchers craft ‘origami DNA’ to control virus assembly
Researchers have used DNA ‘origami’ templates to control the way viruses are assembled. The global team behind the research, published in Nature Nanotechnology, developed a way to direct the assembly of virus capsids – the protein shell of viruses - at physiological conditions in a precise and programmable manner. ...
