Fig. 38. Substrate dependence of the PS/PMMA domain structure spin-cast from THF a-c on SiOx d-f on octadecyl mercaptane (ODM) [352]. The SFM images have lateral dimensions of 14x14 pm2. a,d as spin cast b after immersion in cyclohexane to remove PS. e after immersion in acetic acid to remove the PMMA-rich phase. The cross-sections (c,f), which were recorded along the lines in (a,b,c,d), reveal the vertical distribution of the PS (dark grey) and PMMA (light grey) phases. The error bar in (c) indicates the accuracy of the superposition procedure. PMMA preferentially adsorbs on the more polar SiOx surface to form a homogeneous layer next to the substrate. On the ODM a PS/PMMA bilayer is observed. Courtesy of U. Steiner...

The SAM consists of a mixture of octadecyl mercaptan (OM) and two short chain disulfides, which form -S-CH2-CH2-CH2-COO" and -S-CH2-CH2-NH3+ on the surface. The short chain, charged modifiers may provide defects, or pockets, in the OM layer where the enzyme may adsorb through electrostatic interactions. At oxidizing potentials, the electrode generates a catalytic current at densities up to about 10 pA/cm when exposed to fructose solution. The enzyme electrode exhibits a response time well under a minute and the calibration curve is linear at fructose concentrations up to 0.8 mM. The biosensor prototype exhibits low susceptibility to positive interference by ascorbic acid indicating that this construct could be useful for fructose analysis of citrus fruit juice.

Using the silver-coated gold QCM electrodes functionalized with a controlled submonolayer surface coverage of octadecyl mercaptan and the dual chamber dialysis cell for bilayer deposition, over 95% of the electrodes work—i.e., they are successfully modified with functional cytochrome c oxidase [69]. Figure 11 shows cyclic voltammograms conducted at three different representative oxidase-modified electrodes and a control experiment for a lipid bilayer membrane containing no immobilized oxidase [69]. Some difference in peak current and wave...
