Assembled Biohybrid Light-Harvesting Antennas (image) Washington University in St. Louis Caption The dyad modules assemble into rings (side view, above left, and top view, above right) that pack many pigments together for light harvesting. Because of the additional pigments attached to the dyads, the antennas absorb more of the sun's light than natural systems. Credit Hunter/Holten/PARC Usage Restrictions Please credit.
