Gold and TiO₂ Nanostructurated Surfaces for Assembling of Electrochemical Biosensors

Figure 2

Calibration curve of (a) glucose biosensor based on TiO₂-modified Si electrodes, and (b) H₂O₂ biosensor based on TiO₂-modified Si electrodes. Inset graphs show typical amperometric response of the biosensors to successive injection of glucose and H₂O₂ into stirring 0.1 M phosphate buffer solution at pH 7.0.
