Nanofibers and morphology shifting micelles

A method of altering a morphology of a micelle from a rod to a sphere, said method comprising, subjecting said micelle to a stimulus wherein said micelle comprises a plurality of aggregated amphiphilic molecules each having a single-strand nucleic acid hydrophilic portion comprising at least one nucleic acid moiety covalently linked to a polymer within said amphiphilic molecules, and a hydrophobic portion, and wherein said stimulus is a single-strand nucleic acid hydrophilic portion binder capable of hybridizing to one of said single-strand nucleic acid hydrophilic portions thereby altering the morphology of said micelle from a rod to a sphere.
