Used in bioelectronic devices due to its ability to convert light into electrical signals. Applied in optical data storage and holographic memory systems because of its high photo-stability and fast switching between states. Investigated for use in artificial retinas and other neural interface technologies thanks to its light-sensitive ion-pumping function. Also explored in biosensors and environmental monitoring for detecting light and pH changes. Its self-organizing structure in lipid membranes supports development of biocompatible nanomaterials and molecular machines.
