We spent many years studying the high resolution electronic spectroscopy of porphyrins. Recently, however we began to study the dynamics and thermodynamics associated with the formation of RNA construct-peptide complexes using single molecule detection methods, such as dual color fluorescence correlation spectroscopy (DCFCS) and single pair fluorescence resonance energy transfer (spFRET).
