A nanofabrication method is presented that not only forms nanoparticles but also organizes them. Lee et al. (p. 892; see the Perspective by Ober) genetically engineered a coat protein of M13 bacteriophage with a specificity for the surfaces of ZnS nanoparticles. The bacteriophage, being long rigid structures, can form liquid-crystalline phases in solution, and thus the attached nanoparticles can assemble into ordered layered structures.
