Moreover\, the combination of\ndiffere nt precursors provides a certain control over the physicochemical properti es of the\nsolvent (e.g. solvent polarity and charge density). Thus\, DES are regarded as task-specific\n“cocktails”\, where the properties of t he solvent can be tuned to suit particular applications.\nRecent developme nts have shown the ability of DES to support amphiphile self-assembly\,\nb ringing the possibility to develop sustainable alternatives for surfactant templating\, drug\ndelivery and biosensing\, among others. Here we will e xplore the self-assembly of surfactants\nin DES as probed using small-angl e neutron scattering. The increase of charge density in the\nsolvent is sh own to promote micelle growth through electrostatic screening in compariso n to\nmore neutrally charged DES environments.[2\,3] In addition\, the com bined effect of\nhydrophobic and electrostatic interactions through the ad dition of hydrotropic salts leads to\na profound change in micelle shape\, resulting in the formation of worm-like micelles.[4]\nFinally\, our lates t results in the study of long-range colloidal interactions in DES will be \npresented. Aiming to gain a better understanding of the fundamental aspe cts of amphiphile\nself-assembly in these solvents\, we will present detai ls of the micellisation with varied\nphysicochemical properties of the sol vent\, salt addition and counterion substitution.\n[1] B.B.
