L'obiettivo di questo esperimento è quello di determinare e controllare la dimensione, la forma e la stabilità del amphiphiles discotici auto-assemblati in acqua. Per polimeri a base acquosa supramolecolari tale livello di controllo è molto difficile. Noi applichiamo una strategia con entrambe le interazioni ripugnante e attraente. Le tecniche sperimentali applicate a caratterizzare questo sistema sono ampiamente applicabile.
