How does the photosynthetic antenna efficiently utilize sunlight? Chlorosomes are light-harvesting systems in green sulfur bacteria, composed of numerous bacteriochlorophyll (BChl) molecules. The inherent heterogeneity in the number and assembly of BChls within each chlrosome should be directly related to their efficient light-harvesting function. Single-particle spectroscopy is particularly well-suited to this challenge because it can detect specific and distinctive spectral features of individual molecules that cannot be observed in ensemble-averaged spectra. The talk will discuss the above topics on the example of natural chlorosomes as well as biomimetic light-harvesting nanotubes.
