The cover picture shows a microfluidic channel between two reservoirs made of SiN on a SiO 2 substrate. In the channel lies several microelectrodes made of platinum. ZnO nanowires are grown from nanoparticles deposited on the electrodes using AC dielectrophoresis. The device shows n‐type transport characteristics with 4 to 6 orders of magnitude modulation of conductance. ZnO nanowires are thereafter functionalized with 3‐aminopropyltriethoxysilane to be used as pH sensors.
