What Nanostructures Mean for Colors

What Nanostructures Mean for Colors

Ever wonder how peacocks and other animals get their signature colors? Or how the feathers on peacocks always appear blue, even if you look at them from different angles? It’s not because of color pigments, but rather special nanostructures. Due to their make-up, these nanostructures reflect light in a unique way so that the light waves intersect and create vibrant colors. Now, a team of researchers at the Karlsruhe Institute of Technology has discovered more about how these structures work and their possible benefits for us.

Scientists studying blue tarantulas found the spiders’ color was the result of their hairs. These, they discovered, were made up of multiple layers and resembled the structures of flowers. Using computer analyses, the researchers began noting how the hairs reflected light and attempted to copy them with the help of a specialized 3D printer that could create micro and nano pieces. They successfully created a structure like the hairs that had a viewing angle 160 degrees, meaning that when viewed at any of those angles; it would appear to be the same color. That’s the largest man-made viewing angle ever created so far.

But what does this mean for us? Well, these nanostructures are not only brighter and stronger than other natural colors, they are also non-toxic, unlike pigments. Additionally, scientists on the team believe that in the near-future these could play a big role in the textile industry. Other fields might be slower to adopt these nanostructures, but not because of a lack of possible applications. Currently, there are not many 3D printers capable of making them. Until these become more widespread, using the nanostructures might prove difficult. The scientists, however, are confident that this problem will soon be fixed.

If you’re a researcher studying similar nanostructures, or just trying to create a consistent color, turn to the experts and ensure your colors are what you need them to be. You’re sure to find the perfect color measurement instrument in Konica Minolta Sensing’s extensive catalog. For example, the CM-512m3A and CM-M6 are both easy-to-use and can evaluate color at a number of viewing angles. Make sure you’re ready to measure nanostructure colors with Konica Minolta Sensing.
