Toward 4D printing with structural colors

The colors in the world around us are produced through either absorption of light by molecules (pigmentary colors) or scattering of light by nanostructures (structural colors). Nature provides many spectacular examples of ...

Scientists look to bird feathers for printing colors

In nature, colors play a vital role in behaviors such as pollination, signaling for mating and defense against predators. Colors are also an important factor in scientific research that can provide the basis for novel printing ...

Mass manufacturing of metasurfaces

The mass production of flat optical devices with sub-wavelength structures could soon be a reality, thanks to a metasurface fabrication technique developed by researchers at A*STAR.
