An artist’s rendering of a DNA-based virus trap, represented as gray rods in a short cone-shaped arrangement. One is coated with blue molecules, likely antibodies, that adhere to a virus target. Another image shows to traps coming together to capture a red coronavirus.
“Origami” DNA Traps Could Keep Large Viruses From Infecting Cells
By engineering structures out of DNA, scientists could potentially prevent larger viruses, like coronaviruses and influenza viruses, from interacting with cells.
