According to the Guinness Book Of World Records, Scientists have set the smallest printed color image of a clownish in a sea anemone, which is as thin as the cross-sectional area of the human hair, which is even invisible to the human eye. The picture of the clownish, measures a minuscule of 80 µm x 115 µm and 0.0092 mm2 in area.
A special microscope is needed in order to see it with our naked eyes which was declared by the official witnesses. To create the picture, of the clownish the team had used the technology of 3D Nano Drip printing, invented at ETH Zurich and now commercialized by the spin-off company Scrona. The image real-life color quality is the result of Quantum dots (QDs).
Quantum dots are the nanoparticles that emit light of a very specific color. The size is tuned so that the color is freely engineered for example, from orange to yellow. Quantum dots (QDs) are the dots which are very intense in their color appearance, this is the reason why they currently make a strong debut in flat panel displays.
It is so tiny that is invisible to the human eye which requires a special microscope to check what’s really visible there. The picture of the clownish is a result of the engineering company Swiss ETH Zurich’s real efforts who has used 3D Nano Drip technology of printing, by using Quantum dots, as told before it acts as nanoparticles that emit light of a specific color.
The achievement suggests many new ways of the nanostructured materials which are used in optics, display sector.Thereby, adjusting the size of different colors to be produced such as green, red, blue dots were created in the world breaking image record. Scrona is running a campaign on Kickstarter through January 9, 2016, offering micro-prints and miniature microscopes to view the images.
