Novel DNA-peptide structure holds promise for multicoloured roll-up displays
Researchers believe a novel DNA-peptide structure can be used to produce thin, transparent, and flexible screens, a development that could lead to roll-up electronic displays.
The research from Tel Aviv University is said to harness bionanotechnology to emit a full range of colours in one pliable pixel layer compared to the several rigid layers that constitute today’s screens.
“Our material is light, organic, and environmentally friendly,” said Prof Ehud Gazit, from the Department of Molecular Microbiology and Biotechnology at TAU’s Faculty of Life Sciences. “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 minimise production costs dramatically, which will lead to lower prices for consumers as well.”
Prof Gazit conducted the research with doctoral student Or Berger in collaboration with Dr Yuval Ebenstein and Prof Fernando Patolsky of the School of Chemistry at TAU’s Faculty of Exact Sciences.
For the purpose of the study, a part of Berger’s Ph.D. thesis, the researchers tested different combinations of peptides: short protein fragments, embedded with DNA elements which facilitate the self-assembly of a unique molecular architecture.
