Nanopracticle Gene Therapy (IMAGE) Johns Hopkins Medicine Caption In experiments in rats and mice, two Johns Hopkins scientists -- an engineer and an ophthalmologist -- report the successful use of nanoparticles to deliver gene therapy for blinding eye disease. A uniquely engineered large molecule allows researchers to compact large bundles of therapeutic DNA to be delivered into the cells of the eye.
