Characteristic curve of the surface tension for aqueous surfactants solution. A) schematic presentation of the peptide amphiphile with the hydrophobic C₁₆-alkylchain and the hydrophilic peptide headgroup forming micelles by self-assembly above the critical micelle concentration (CMC). B) idealised curve of surface tension as a function of surfactant concentration with the CMC representing the point, where surfactant molecules start to form aggregates known as spherical micelles, with further increasing concentration, the micelles change the shape to cylindric forms.
