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

Polymer-based responsive structural color materials are polymers with ordered
microstructures that can change colors. They offer unique advantages and present a novel …

Nanocellulose has a wide range of applications in the field of functional materials, and it has
piqued the interest of researchers for some time. This is because nanocellulose inherits the …

Patterning of photonic crystals to generate rationally designed color‐responsive materials
has drawn considerable interest because of promising applications in optical storage …

Invisible photonic crystal (PC) pattern with encrypted and discoverable information is
potentially useful for anti-counterfeiting labels, but it is still a big challenge to realize strict …

In this paper, we report a facile strategy to combine magneto-responsive photonic crystal
(MRPC) ink with 3D printing technology. The building blocks of MRPC are based on Fe3O4 …

Advanced multiplexing optical labels with multiple information channels provide a powerful
strategy for large‐capacity and high‐security information encryption. However, current …

Information encryption strategies have become increasingly essential. Most of the
fluorescent security patterns have been made with a lateral configuration of red, green, and …

Developing multi-mode luminescent anti-counterfeiting materials is one of an efficient tactics
to ensure the security of important documents and information. Herein, multi-mode …

While structural color materials are widely exploited in anti‐counterfeiting applications, it still
