Biomimetic materials exploit the biomineralization process to form functional organic-inorganic hybrid nanostructures. In this work, we mimicked the biomineralization process by the de novo design of an amyloid-like peptide that self-assembles into nanofibers. Chemically active groups enhancing the affinity for metal ions were used to accumulate silicon and titanium precursors on the organic template. The self-assembly process and template effect were characterized by CD, FT-IR, UV-vis, fluorescence, rheology, TGA, SEM, and TEM. The self-assembled organic nanostructures were exploited as a template to form high-aspect-ratio 1-D silica and titania nanostructures by the addition of appropriate precursors. Herein, a new bottom-up approach was demonstrated to form silica and titania nanostructures that can yield wide opportunities to produce high-aspect-ratio inorganic nanostructures with high surface areas. The materials developed in this work have vast potential in the fields of catalysis and electronic materials. © 2011 American Chemical Society.EnglishBiomineralization processBottom up approachDe novo designElectronic materialsHigh aspect ratioHigh surface areaInorganic nanostructuresOrganic nanostructuresOrganic templatesOrganic-inorganic hybrid nanostructuresSelf assembly processSelf-assembledSelf-assembled templateSEMTEMTemplate effectsTitania nanostructuresTitanium precursorsAspect ratioBiological materialsBiomimeticsBiomineralizationHybrid materialsMetal ionsNanostructuresOcean habitatsSilicaTitaniumTitanium dioxideBiomimetic materialsnanomaterialsilicon dioxidetitaniumarticlechemical structurechemistrycircular dichroisminfrared spectroscopyliquid chromatographymass spectrometrynanotechnologyscanning electron microscopytransmission electron microscopyultrastructureX ray diffractionChromatography, LiquidCircular DichroismMass SpectrometryMicroscopy, Electron, ScanningMicroscopy, Electron, TransmissionMolecular StructureNanostructuresNanotechnologySilicon DioxideSpectroscopy, Fourier Transform InfraredTitaniumX-Ray DiffractionArticle10.1021/la104518g
