Release date: 2016-12-20 Age-related macular degeneration (AMD), also known as age-related macular degeneration, is one of the important eye diseases associated with age-related blindness. Age-related macular degeneration is the primary cause of visual impairment in developed countries. In China, due to the aging of the population, other causes of blindness have been obtained or strengthened, and age-related macular degeneration has increasingly become an important blinding eye disease. According to the British Broadcasting Corporation reported on December 15, patients with age-related macular degeneration usually have to undergo direct eye drug injection for several months. Researchers say metal nanotechnology can help reduce the number of injections required for common treatments. According to the report, Australian and Chinese researchers believe that metal nanoparticles can help humans to deliver ocular drugs. They recently published their research in the Journal of Applied Chemistry. The research is to test how the hydrogel filled with metal particles reacts under exposure. Nanoparticles, usually 1,000 times thinner than human hair, are too small to be observed through a microscope. The researchers found that the hydrogel in the exposed environment softens after warming and releases a dose of vision-repairing drug. When the light disappears, the process reverses and the gel gradually hardens and stops drug delivery. The study said that the biological activity of this protein-based drug was "highly retained" after release. Currently, researchers are conducting preliminary safety tests on rabbits, but further research is needed to consider human trials. Source: World Wide Web
