Engineers employed at Glasgow University have developed a breakthrough from of nano-technology that can be used to produce anti-counter fit currency. The scientists declare that this could make waves through the digital imaging and data storage sectors and the technology uses different filters that display various colors that are dependent on the orientation of the light that hits them.
Dr. Alasdair Clark explains that in addition to the financial implications, the new technology also affects digital photography. Because the colors in the paper do not fade, even when exposed to harsh sunlight over a long period of time, it can be used to achieve an 'ultra-high resolution'. This could help to create the possibility of new types of color filters for digital photography.
The research is still underway and is supported by The Engineering and Physical Sciences Research Council and The Royal Academy of Engineering and their paper is already published in Advanced Functional Materials.
