Book excerpt: Taking the control over supramolecular and chiral forces has always been a challenge for the scientific community. Dynablocks are amphiphiles based on reversible imine covalent bond that, in water, self-assemble in mesophases. With a new charged aldehyde, charged dynablocks were used to tune the surface of the assemblies directing the charged heads inward or outward, changing the PEG units and the pKa of the amines. Moreover, we continued the study on focusing the interest on self-replicating properties (autopoiesis), topic that provides insights for the first replicators that could have appeared in the prebiotic Earth. Non-charged dynablocks were instead employed for the study of structures in high concentration and for chiral amplification. In this latter, peptide amphiphilic dynablocks acted as gelators with a typical 3D intertwined network matrix. A supramolecular twist was observed and a chiral amplification in the structures morphologies was detected in AFM and TEM pictures.
