The authors demonstrate a strategy to enhance the magnetic responsiveness of self-assembled peptide nanostructures by combining the concepts of perfect alpha-helix and rod-coil supramolecular building blocks. They develop a monomeric, nonpolar, and perfect alpha-helix and use it as the rod block of rod-coil amphiphiles for fabricating responsive assemblies.
Because organic molecules and materials are generally insensitive or weakly sensitive to magnetic fields, a certain means to enhance their magnetic responsiveness needs to be exploited. Here we show a strategy to amplify the magnetic responsiveness of self-assembled peptide nanostructures by synergistically combining the concepts of perfect alpha-helix and rod-coil supramolecular building blocks. Firstly, we develop a monomeric, nonpolar, and perfect alpha-helix (MNP-helix). Then, we employ the MNP-helix as the rod block of rod-coil amphiphiles (rod-coils) because rod-coils are well-suited for fabricating responsive assemblies. We show that the self-assembly processes of the designed rod-coils and disassembly of rod-coil/DNA complexes can be controlled in a magnetically responsive manner using the relatively weak magnetic field provided by the ordinary neodymium magnet [0.07 similar to 0.25 Tesla (T)]. These results demonstrate that magnetically responsive organic assemblies usable under practical conditions can be realized by using rod-coil supramolecular building blocks containing constructively organized diamagnetic moieties. Organic molecules and materials are generally insensitive or weakly sensitive to magnetic fields due to their small diamagnetic force. Here, the authors show a strategy to amplify the magnetic responsiveness of self-assembled peptide nanostructures by synergistically combining the concepts of perfect alpha-helix and rod-coil supramolecular building blocks
