Kloxin1,3, Jeffery G. Saven2, Darrin J. Pochan1* Programmable control of protein or colloidal nanoparticle self- assembly into targeted nanostructures, while maintaining stability across extreme pH conditions, remains a major challenge. We designed coiled- coil bundlemer peptide nanoparticles that form ordered, hierarchical materials across an unusually broad pH range (1, 7, and 14) dependent on patchy surface charge display. Nematic liquid crystal formation was observed at low concentration (~0.5 to 4 weight %) at pH 1 and pH 14, whereas higher concentration at pH 1 yielded hexagonal columnar phases. …
