DNA Origami Traps Treat Viral Infections

The tiny traps are in the shape of an icosahedron, which consists of 20 triangular planes. The outer surfaces are irradiated with UV light and treated with polyethylene glycol and oligolysine, which prevent them from degrading inside the body. In tests, the structures remained stable in a serum for 24 hours and trapped two types of viruses, preventing them from infecting human cells. The next step is to test the structures in mice and then humans.
