“…By using the electrochemical impedance technique, Garcia-Jareno et al [14,15] have demonstrated that protons play an important role in the kinetics of the electron transport by hopping and that the solvent contribution is necessary to accompany counter ions. Kim et al [16] have reached the same conclusion in 2001 by cyclic electrogravimetry.…”
An amperometric biosensor based on Prussian blue (PB) modified indium tin oxide (ITO) electrode was developed. The roughness of PB film which affects the electrocatalytic properties of PB film was controlled by varying deposition voltage and time. Atomic force microscopy (AFM) was used to measure the roughness of PB films deposited under various conditions. We used Capillary electrophoresis (CE) method to make the analytes flow through the micro channel made of polydimethylsiolxane (PDMS). Compared with sensor using bare ITO electrode, the sensor using PB modified electrode has shown better sensitivity. In addition, we could improve the detection limit of the sensor by depositing smoother PB film.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
