Continual reproduction of self-assembling oligotriazole peptide nanomaterials. [PDF]

, 2017
Autocatalytic chemical reactions, whereby a molecule is able to catalyze its own formation from a set of precursors, mimic nature's ability to generate identical copies of relevant biomolecules, and are thought to have been crucial for the origin of life.
