TL;DR: Structural colors traditionally refer to colors arising from the interaction of light with structures with periodicities on the order of the wavelength as mentioned in this paper, and have been broadened to include other colors.

TL;DR: In this paper, a shape memory polymer (SMP) photoresist based on Vero Clear achieving print features at a resolution of ~300nm half pitch using two-photon polymerization lithography (TPL).

TL;DR: A new SMP photoresist based on Vero Clear achieving print features at a resolution of ~300 nm half pitch using two-photon polymerization lithography (TPL) enabled the study of shape memory effects to achieve large visual shifts through nanoscale structure deformation.

TL;DR: In this article, a color and grayscale generation approach based on the tuning of a single nanostructure geometry is presented. But, achieving different shades of gray and control of color saturation remain challenging.

TL;DR: The potential to selectively reveal more than one set of color patterns is demonstrated by rotating a microlens array relative to a print containing three overlapping arrays of structural color patterns in 10 ° steps, each pattern array can be distinctly revealed with minimal crosstalk.
