Hollow nano-objects made of DNA could trap viruses and
render them harmless

To date, there are no effective antidotes against most
viral infections. An interdisciplinary research team at the
Technical University of Munich (TUM) has now developed a new
approach: they engulf and neutralize viruses with nano-capsules
tailored from genetic material using the DNA origami method. The
strategy has already been tested against hepatitis and
adeno-associated viruses in cell cultures. It may also prove
successful against corona viruses.
