Researchers at IBM and the Institute of Bioengineering and Nanotechnology (IBN) in Singapore have created a macromolecule––one giant molecule made of smaller subunits––that might treat multiple types of viruses and prevent infection.

According to a paper published in Macromolecules, the macromolecule warded off viruses such as influenza, dengue and Ebola successfully in a lab environment. Importantly, the macromolecule remained effective even after the viruses mutated. Researchers plan to test the Zika virus next, and they believe its similarities to a form of dengue already tested will result in yet another successful trial.
