Mechanical Property of TiO₂ Nano-Tubes Surface Based on the Investigation of Residual Stress, Tensile Force and Fluid Flow Shear Stress: For Potential Application of Cardiovascular Devices.

The TiO2 nanotube has been anticipated for potential application for cardiovascular implanted devices for its excellent drug loading/release function and biocompatibility. However, its mechanical behavior has rarely been studied as the cardiovascular devices. The tube length is a crucial factor which not only decides the drug loading ability but also influences the devices' mechanical behavior.
