• microporous extrinsic semiconductor channels, through fractional deposition of the nanostructures. These nanostructures do not form a surface coating but rather act as independent nanostructured sites capable of strongly directed interaction with a given analyte and subsequent rapid electron transduction. In

• components are separable, they can be combined to provide an enhanced versatility versus a single or mixed metal-oxide surface coating. In concert with the IHSAB principle, this approach leads to an optimized and simpler interface. Treatment of the semiconductors with nanostructured photocatalysts can be

• them with a uniform hydrophobic surface coating. For that purpose the surfaces were dipped in Antispread (F2/200 Fluorcarbon 60, Horb-Ahldorf, Germany) for 10 s which forms approximately 40 nm thin layers on the substrate surfaces (product information). After drying for 30 minutes, the hydrophobized
