Titanic Nanowires Embedded Into a Macro Titanium Plate


Researchers have developed a simple method of fabricating a tough coating of titanate nanowire bioscaffolds on a solid titanium substrate. As titanium is a biocompatible material, the new titanate nanowire surface opens the possibility of medical applications. The bottom of the nanowires are embedded into a macro-scale titanium plate, and then grow together at their top ends to produce a bioscaffold with interconnected macropores of 2-10 micrometers. The mesh mimics the natural extracellular matrix and exhibits good cellular compatibility, mechanical toughness, and structural robustness. The porous coating has potential for developing new tissue regeneration, drug delivery, and photocatalysis nanotechnologies. In addition to the bio-medical applications, the embedded nanowire titanium surface also has other possible applications, including,

Stenting with on-site drug release for anti-restenosis

Providing a bio-compatible mechanical support and matrix for the growth of new bone cells

A dental material with on-site drug release and improved implantation for dental replacements

Airplane external coating to reflect/adsorb electromagnetic waves

Ship coating to release chemicals for anti-fouling
