Evenly spaced arrays : The unique molecular architecture of a self‐assembled polypeptide template allows the electrostatic deposition of nanoparticles with uniform interparticle spacing. The hierarchical self‐assembly mode of the polypeptide results in the display of charged patches at periodic distances along the length of the fibril architecture (see picture).
