We present a cellular test device based on Nb:TiO2 (niobium dooped titania) transparent conductive oxide (TCO) as bio-electrodes. The device is intended to easily provide electrical stimuli to a given cell tissue and to monitor its response. The Nb:TiO2 thin film deposition were performed with combinatorial chemical beam epitaxy (C-CBE) which allows for linear and well controlled gradients of both Nb concentration (ranging from 3% to10%) and oxide thickness in predefined directions (usually orthogonal). We have systematically characterized the Nb:TiO2 films with Atomic Force Microscopy, Scanning White-light Reflectometry, and sheet resistance Finally, we show the device, i.e the electrodes design and patterning in order to perform to electrical stimuli to the various ways to measure the cell’s response.
