New Photonics Based on Bio Mimicry of Fish Guanine Platelet

Abstract

Guanine molecule is one of DNA base molecules and is utilized for a material controlling the strong light reflection on body surface of animals, such as fish, frog, spider, chameleon and plankton. This review summarizes general features of fish guanine platelets, and focuses on the recent topic of novel optical properties of the platelets. In addition, utilization of bio-reflecting biomaterials for light control is discussed. Investigating dynamic optical phenomenon which can be observed in living creature may provide more attractive nature of micro-particles. Particularly, fish guanine platelets exhibit a specific directionality in light reflection and diffraction. This novel optical behavior can be applied for micro-imaging of dynamic motions.
