Bright white coloring of Pacific cleaner shrimp revelead
Scientists at the Ben-Gurion University of the Negev, Israel have made a significant discovery to explain the bright, white-colored stripes displayed by the Pacific cleaner shrimp. Their findings, published in Nature Photonics, shed light on the molecule responsible for this phenomenon and highlight its relevance to the development of photonic materials.
Bright white stripes observed on Pacific cleaner shrimp have interesting photonic materials properties with applications in solar cells, sensors, and optical displays. Through their investigations, the team identified that the enhanced light propagation arises from densely packed nanospheres made of isoxanthopterin molecules located below the shrimp’s skin. Part of the experiments was performed at the X06SA-PXI beamline at the Swiss Light Source.
The study provides fundamental insights into the role of optical anisotropy in light scattering and suggests potential applications in the development of novel, organic whitening materials.
