4 36 BI O INS PIRED P H O T O NI C S Structural color has been more widely studied in some organisms than in others and there are many excellent review articles to be found. 3 Describing Biological Photonic Structures The photonic systems found in biological organisms range from ­simple, quasi-ordered structures to highly ordered complex architectures. They are typically constructed of a biomaterial, which acts as a high index of refraction material, and air, which acts as the low index of refraction material.

The scale of the hierarchical structures responsible for structural color, for example, can be on the order of only a few nanometers up to hundreds of nanometers and incorporated in even larger structures up to micron and mm scale. Developing fabrication methods capable of fabricating the intricate detail called for some of these systems is an ongoing desire. 53 In this method, the biological structure a precursor is allowed to infiltrate the structure. After removal of the original biological structure, the subsequent inverse structure can be analyzed or used as a mold to grow a replica of the original structure.

From Vignolini, S. , J. R. Soc. Interface, 10, 87, 2013. 43 Care should also be taken that neither the illumination intensity nor the exposure time damages the sample. 43 Several passive and active color systems have polarization information (both linear and circular), and some eyes, such as some spider eyes, can also detect light polarization. For samples that strongly scatter light, any polarization information of the scattered illuminating light will be lost. 3 Challenge of Working with Live Specimens Carrying out experiments with small biological specimens sometimes requires creative thinking and great inventiveness.
