Colloidal self-assembly refers to a solution-processed assembly of nanometer-/micrometer-
sized, well-dispersed particles into secondary structures, whose collective properties are …

Counterfeiting is a growing global issue causing severe negative impacts on the social
economy and posing serious security threats to individuals and communities. However, the …

The counterfeiting of goods is growing worldwide, affecting practically any marketable item
ranging from consumer goods to human health. Anticounterfeiting is essential for …

Organisms in nature have evolved unique structural colors and stimuli‐responsive functions
for camouflage, warning, and communication over millions of years, which are essential to …

Abstract Four-dimensional (4D) printing of shape memory polymer (SMP) imparts time
responsive properties to 3D structures. Here, we explore 4D printing of a SMP in the …

Chameleons use a non-close-packed array of guanine nanocrystals in iridophores to
develop and tune skin colors in the full visible range. Inspired by the biological process …

Structural colors widespread in nature have been theoretically in‐depth studied and
manufactured through the artificial approaches such as self‐assembly and nanolithography …

Efficient and large scale printing of photonic crystal patterns with multicolor, multigrayscale,
and fine resolution is highly desired due to its application in smart prints, sensors, and …

The colors of photonic crystals are based on their periodic crystalline structure. They show
clear advantages over conventional chromophores for many applications, mainly due to …

Colloidal arrays show structural colors through wavelength-selective diffraction. The
structural colors are dynamically tunable with mechanical deformation for a non-close …
