Reflectin proteins are proteins derived from cephalopods (certain species of squid) which have unusual optical properties. Disclosed herein are thin films of reflectin proteins which can be tuned to reflect infrared light. Advantageously, the films can be tuned dynamically over short time scales, to reflect at different wavelengths. Disclosed herein are novel infrared-reflective coatings, methods of making such coatings, and infrared-reflective objects such as textiles, building materials, and camouflage materials.

Dynamic infrared-reflective materials based on reflectin films

The disclosed invention relates to novel materials and associated methods for conducting protons, such materials comprising cephalopod proton-conducting proteins such as reflectins. The protonic conductivity of such cephalopod proton-conducting proteins may be modulated by the application of an electric field. The invention further encompasses protonic transistors comprising a cephalopod proton-conducting protein channel. The transistors and related devices of the invention are amenable to use in biological systems for the sensing or manipulation of protonic flows within the biological system.
