    We have surpassed an important milestone by preparing ZeoFRET® materials with a donor-to-acceptor ratio above 50. Materials can now be synthesized with channels containing roughly 100 donor dyes (light absorption) and one acceptor dye (light emission) at each end. This allows us to further maximize light-harvesting while keeping self-absorption losses to a minimum.
