In the efforts to find a biodegradable, environmentally-friendly source for next generation BioLED screens, researchers have focused their sights on salmon sperm. Who wouldn’t want that job?
The DNA of salmon sperm is apparently perfect for the technology because it allows two orders of magnitude in terms of efficiency, light, and brightness. It is also considered a waste product by the fishing industry; thrown away “by the ton” according to the project leader, Professor Andrew Steckl. From the article,
“In considering materials to introduce to affect the movement of the electrons, Steckl evaluated the source of materials with an eye to supply, especially materials that do not harm the environment. ‘Biological materials have many technologically important qualities — electronic, optical, structural, magnetic,†says Steckl. “But certain materials are hard for to duplicate, such as DNA and proteins.’ He also wanted a source that was widely available, would not have to be mined, and was not subject to any organization or country’s monopoly. His answer? Salmon sperm.”
The DNA in the sperm acts as a barrier to hold the electrons in place; therefore allowing the scientists to control the amount of light that is emitted. “The story continues,†says Steckl, again smiling. “I’m receiving salmon sperm from researchers around the world wanting to see if their sperm is good enough.â€
While BioLED displays are still several years off, it’s great to see the industry moving towards environmentally-friendly biodegradable sources. No doubt, however, salmon are less than enthused. Hit the jump for more.
