From smartphones and tablets to computer monitors and interactive TV screens, electronic displays are everywhere. As the demand for instant, constant communication grows, so too does the urgency for more convenient portable devices -- especially devices, like computer displays, that can be easily rolled up and put away, rather than requiring a flat surface for storage and transportation.

A new Tel Aviv University study, published recently in Nature Nanotechnology, suggests that a novel DNA-peptide structure can be used to produce thin, transparent, and flexible screens. The research, conducted by Prof. Ehud Gazit and doctoral student Or Berger of the Department of Molecular Microbiology and Biotechnology at TAU's Faculty of Life Sciences, in collaboration with Dr. Yuval Ebenstein and Prof. Fernando Patolsky of the School of Chemistry at TAU's Faculty of Exact Sciences, harnesses bionanotechnology to emit a full range of colors in one pliable pixel layer -- as opposed to the several rigid layers that constitute today's screens.

"Our material is light, organic, and environmentally friendly," said Prof. Gazit. "It is flexible, and a single layer emits the same range of light that requires several layers today. By using only one layer, you can minimize production costs dramatically, which will lead to lower prices for consumers as well."
