MALDI-imaging enables direct observation of kinetic and thermodynamic products of mixed peptide fiber assembly.Controlling the self-assembly of multicomponent systems provides a key to designing new materials and understanding the molecular complexity of biology.  Here, we demonstrate the first use of MALDI-imaging to characterize a multicomponent self-assembling peptide fiber.
