Here, we describe the structural screening of peptide amphiphiles with autocatalytic self-replication, which mimics the perpetuation mechanisms of living matter. Our design uses two reactive precursors to generate self-assembling peptide amphiphiles, which form micelles that catalyse their own synthesis. A collection of precursors with varying sizes was screened combinatorially, revealing a minimal tripeptide amphiphile required to trigger autocatalytic self-replication. These results contribute to the structural simplification of synthetic supramolecular monomers with life-like behaviour.engjournal article10.1002/syst.2024000942570-4206open access
