First Membrane Controlled By Light Developed

Posted by timothy on from the my-eyelid-aside dept.

An anonymous reader writes with this excerpt: "A new membrane developed at the University of Rochester's Laboratory for Laser Energetics blocks gas from flowing through it when one color of light is shined on its surface, and permits gas to flow through when another color of light is used. It is the first time that scientists have developed a membrane that can be controlled in this way by light."

    My first thought is that it would be useful to automatically control aspiration/respiration of something during daylight hours, with the sun providing ultraviolet light. Just can't think of an immediate application.
