Biomimetic camouflage inspired by cephalopods

Cephalopods are known as the chameleons of the sea - they can alter their skin's coloration, pattern, texture, and reflectivity to blend into the surrounding environment. Despite much research effort, there are few known strategies (natural or artificial) for emulating the unique dynamic reflectivity and coloration of cephalopods. We have developed an approach to the fabrication of stimuli-responsive cephalopod-inspired thin films with emergent optical properties. We have furthermore enhanced the properties of such films through a synergistic combination of bioconjugate chem., bottom up self-assembly, and top down nanofabrication. Our findings hold significant implications for the development of reconfigurable biomimetic camouflage coatings.
