Why you should listen
At Imperial College London, Molly Stevens heads a highly multidisciplinary research group that designs bioactive materials for regenerative medicine and biosensing. It's fundamental science with an eye to practical applications as healthcare products.
Among the products from her lab: an engineered bone, cardiac tissue suitable for use in transplants, and disease-sensing nanoparticle aggregates that change color in the presence of even tiny quantities of cancer-related enzymes, making early sensing possible. As Stevens told The Lancet: "It's right down at the nanoscience level. It's really exciting stuff, but it actually results in something very tangibly useful."
