In this talk, I will present our recent findings of flow-regulated anodic growth of TiO2 nanotubes in microfluidics and show that flow not only controls the diameter, length, and crystal orientations of TiO2 nanotubes but also regulates the spatial distribution of nanotubes inside microfluidic devices. Strikingly, when a Ti thin-film is deposited on silicon substrates and anodized in microfluidics, both vertically- and horizontally-aligned (relative to the bottom substrate) TiO2 nanotubes can be produced. I will discuss the mechanism of flow-regulated mass transport in this process and show how the same principle could be potentially applied to control dendrite formation during electrodeposition
