This issue of MRS Bulletin covers the molecular characterization of inorganic-binding peptides; their further tailoring using post-selection genetic engineering and bioinformatics; and finally demonstrates their utility as molecular synthesizers, erectors, and assemblers (i.e., fundamental building blocks in programmed formation of functional materials for areas ranging from practical engineering to medicine). In nature, the molecular-recognition ability of peptides and, consequently, their functions are evolved through successive cycles of mutation and selection. Using biology as a guide, we can now select, tailor, and control peptide–solid interactions and exploit these in novel means. Researchers have adopted combinatorial mutagenesis protocols to genetically select short peptides with specific affinity to a variety of practical materials including metals, ceramics, and semiconductors.
