Macroporous biomineralized composites in the form of thin slices of tooth dentine were used to prepare oriented arrays of high aspect ratio copper microwires by template-directed electrochemical deposition. The coaligned wires were 1 to 4 mu m in thickness, and spatially separated throughout the dentine matrix to produce a metallized inorganic-organic biocomposite that exhibited ohmic conductivity and enhanced mechanical hardness. Utilization of porous biomineral templates for the crystallization of metallic microwire arrays offers a novel step towards the low temperature fabrication of multi-functional conductive hybrid composites with integrated bioinspired properties.
