Publishing their work in the journal Science Advances the team showed that they successfully engineered new modified molecules using natural glucose derivatives, known as cyclodextrins. The molecules attract viruses before breaking them down on contact, destroying the virus and fighting the infection.

Dr Samuel Jones, from The University of Manchester and a member of the Henry Royce Institute for Advanced Materials, jointly led the pioneering research with Dr Valeria Cagno from the University of Geneva. “We have successfully engineered a new molecule, which is a modified sugar that shows broad-spectrum antiviral properties. The antiviral mechanism is virucidal meaning that viruses struggle to develop resistance. As this is a new type of antiviral and one of the first to ever show broad-spectrum efficacy, it has potential to be a game changer in treating viral infections.” said Sam.

Professor Caroline Tapparel from the University of Geneva and Prof Francesco Stellacci from EPFL were both also senior authors of the study. Prof Tapparel declared: “We developed a powerful molecule able to work against very different viruses, therefore, we think this could be game changing also for emerging infections.”

The molecule is patented and a spin-out company is being set up to continue pushing this new antiviral towards real-world use. With further testing the treatment could find a use in creams, ointments and nasal sprays or other similar treatments for viral infections. This exciting new material can work to break down multiple viruses making for cost-effective new treatments even for resistant viruses.
