摘要: Micelles of different amphiphiles adopt shapes and internal packing arrangements in water, depending on their chemical structures the conditions medium. Two microenvironmental features, namely polarity microviscosity that aggregate offers to a solubilized molecule, have been monitored using extrinsic fluorescence probes. While differences between micelles spherical rod-like are not always distinct, stacked peptide offer distinctly lower higher solubilizates than others.
