Magnetizing DNA and Proteins Using Responsive Surfactants

DNA chains and their movement in solvent may now be controlled simply by surfactant binding and the switching "on" and "off" of a magnetic field adding a new paradigm to the study and control, condensation and manipulation of DNA (and other biomolecules). Such control is essential for biotechnological applications such as transfection and the regulation of gene suppression, as well as in materials science concerning soft molecular self-assemblies.
