This Review covers photonic crystals (PhCs) and their use for sensing mainly chemical and
biochemical parameters, with a particular focus on the materials applied. Specific sections …

Nature's color has three main sources: pigments, structural colors and bioluminescence.
Structural color is a special one, which is the color produced by micro-or nano-structures …

A new class of materials that are capable of color tunability over 300 nm with a 15° C
temperature change is introduced. The materials are assembled from thermoresponsive …

We have studied the formation of stripe patterned films of ordered particle arrays on
completely solvophilic substrates by using a self-organization technique. In this method, a …

Colloidal crystal (CC) thin films that produce structural colours over a wide visible spectrum
have been self-assembled from silica nanoparticles (SNPs) using a natural sedimentation …

In this paper, the key topics of tunable structural color in biology and material science are
overviewed. Color in biology is considered for selected groups of tropical fish, octopus …

Ordered 2-D structures composed of poly (N-isopropylacrylamide)(PNIPAM) microgel
particles that had regularity on a sub-micrometer length scale were prepared. By using …

Colloidal photonic crystal (PC)-based anti-counterfeiting materials have been widely studied
due to their inimitable structural colors and tunable photonic band gaps (PBGs) as well as …

As a noninvasive eye disease detection and drug delivery device, contact lenses can
improve eye bioavailability and enable continuous drug delivery. In order to monitor the …

Interest in photonic crystals (PCs) is increasing from both the fundamental and technological
viewpoints of photonics research [1] because of the prospects PCs have for manipulating the …
