Solar energy trapping in photosynthesis is achieved by macromolecular membrane assemblies that bind thousands of chlorophylls, held in specific orientations and in close proximity to one another in order to ensure efficient energy and electron transfer. We use atomic force microscopy to determine the membrane organisation of natural chlorophyll-protein complexes. This project aims to extend our current work by using super-resolution optical microscopy to study native photosynthetic membranes and artificial light-harvesting nanoarrays fabricated on surfaces.
