Light-Modulated Cationic and Anionic Transport Across Protein Biopolymers

Light is a convenient source of energy and the heart of light-harvesting natural systems and devices. Here, we show light-modulation of both the chemical nature and ionic charge carrier concentration within a protein-based biopolymer that was covalently functionalized with photoacids or photobases. Using steady-state and time-resolved fluorescence, we explore the... Show more
