Synthesis of inorganic nanomaterials mediated by proteinassemblies

Abstract

Biological materials naturally display a variety of functional structures highly organized at the nanoscale. Various bioassemblies have been shown to template complex, multidimensional inorganic nanoarchitectures that are typically not available by conventional synthetic methodologies. In addition to the various naturally occurring templates, the powerful techniques developed by life sciences are an interesting tool for engineering approaches towards material science. Besides a structural and morphological control during synthesis, biotemplating procedures may add another dimension to inorganic materials such as biofunctionality (e.g., motility functions). This overview is focussed on recent advances in the fabrication of inorganic nanomaterials taking advantage of protein assemblies. It tries to elucidate chemical methodologies and reviews examples of templates based on protein and peptide building blocks that have been successfully employed to manufacture inorganic nanostructures.
