title: Controlling multiple fluorescent signal output in cyclic peptide-based supramolecular systems.
abstract: A multicomponent equilibrium network based on self-assembling alpha,gamma-cyclic peptides with controlled fluorescence output is described. The network takes advantage of the large association constant of alpha,gamma-cyclic peptides and the controlled formation homo- and heterodimers, making use for the first time of excimer/FRET effects in conjunction for studying complex interaction networks. In addition, we study the Dapoxyl/pyrene FRET pair for the first time.
