Electrostatically-directed self-assembly of cylindrical peptide amphiphile nanostructures

Article Abstract:

Theoretical studies of peptide amphiphile nanostructures created by stupp and co-workers is presented ad shown that these amphiphiles exhibit attractive electrostatic interactions between their hydrophilic headgroups. The interactions prevail in their competition with the hydrophobic attraction between the amphiphile tails for the shape of the self-assembly leading to cylindrical micelles of nanoscale dimension.

All-atom numerical studies f self-assembly of Zwitterionic peptide amphiphiles

Article Abstract:

An approach based on all-atom empirical force fold calculations is applied to self-assemblies of Zwitterionic peptide amphiphiles possessing large dipoles in their hydrophilic headgroups. The conclusion states that the structure exhibits the tendency to curve around an axis parallel to the direction of the dipoles and the hydrogen bonds, forming a cylindrical micelle.

Phase diagram for assembly of biologically-active peptide amphiphiles

Article Abstract:

A phase diagram is constructed for self-assembling biologically active peptide amphiphiles. The changing solution conditions have resulted in phase transitions among these structures.
