By copying the texture of insect wings or using new types of materials to create surfaces that kill or inhibit microbes, we could stop infections before they even get into the body. Ten million deaths per year. It’s an unfathomable figure, but one that Gerald Larrouy-Maumus mentions often. It is the potential toll facing the world as disease-causing microbes develop resistance to our best defence against them – antibiotics. Currently, 700,000 people die each year of drug-resistant diseases. Over the past decade or so, the list of medicines we can use against harmful bacteria has been dwindling. At the same time, other disease-causing organisms – fungi, viruses and parasites – are also developing resistance to the drugs we use to tackle them almost as quickly as we can make new ones. It means the illnesses they cause are getting harder to treat.
