The aggregation of Tyr-Phe dipeptide and Val-Tyr-Val tripeptide in aqueous solution and in the presence of SDS and PEO-PPO-PEO triblock copolymer: Fluorescence spectroscopic studies

► For the first time demonstrated that dipeptide and tripeptide form micelles. ► Interactions of these peptides with SDS and PEO-PPO-PEO copolymer were studied. ► Aggregation number of the peptide micelles and their mixed systems were determined. ► Accessibility of DPC quencher was found to be more in dipeptide than tripeptide.
