Recently, Melosh has obtained electrically stable LAJs as large as 9 mm2 by atomic deposition of a nanometer-thick passivating layer of aluminium oxide on top of self-assembled organic monolayers with hydrophilic terminal groups [158,159]. Obviously, interlayers based junctions limit electrical measurements only to organic SAMs less conductive than the protecting layer.

Several useful schemes for attaching nucleic acid probes onto electrode surfaces have thus been developed [2-8]. The exact immobilization protocol often depends on the electrode material used for signal transduction. Common probe immobilization schemes include attachment of biotin-functionalized probes to avidin-coated surfaces [15], self-assembly of organized monolayers of thiol-functionalized probes onto gold transducers [16], carbodiimide covalent binding to an activated surface [17], as well as adsorptive accumulation onto carbon-paste or thick-film carbon electrodes [15-30].

The synthesis of LA-pyrenemethylamine conjugate 393 and its self-assembled organic monolayer formed on a gold surface, based as in previous examples on the anchoring ability of the cyclic disulfide moiety of LA, has been carried out <2000ELA21> for the purpose of the potential design of electrochemical immunosensors of monoclonal antibody-benzo [a pyrene interaction. 

This chapter consists of three sections, following this introduction. The first section summarizes the photocontrol of liquid motion by self-assembled adsorbed Az monolayers (Section 15.2). The second section (Section 15.3) introduces controls of molecular organizations of polymer chains triggered by Langrauir-Blodgett-Kuhn (LBK) monolayers of an Az polymer The final section (Section 15.4) describe the motional function of Az layers themselves, the photoinduced deformation of monolayers, and mass migration of Az polymer film systems. The events discussed in these three parts are illustrated in Figure 15.1. 

The TER-XSW method opens the possibility of using XSW to profile nanoscale metal structures and ion distributions above solid surfaces and at fluid-solid interfaces. Applications of TER-XSW have included direct observation of the diffuse electrical double layer at the charged membrane and electrolyte interfaces (Bedzyk et al. 1990 Wang et al. 2001), structural characterization of self-assembled organic monolayers (Lin et al. 1997), and determining metal ion partitioning at oxide-biofilm interfaces (Templeton et al. 2001). These applications are discussed later in this chapter.

Research on size quantization in colloidal systems was responsible for the development by Bard and coworkers of a new field in photoelectrochemistry, that of nanodot electrodes [19, 20]. An ordered or disordered monolayer or sub-monolayer of nanometer-sized semiconductor particles is attached to a conducting substrate either directly or via a self-assembled organic monolayer. The monolayer acts as a spacer, allowing the distance between the dot and the substrate to be varied. Absorption of light by the semiconductor dots gives rise to processes similar in many ways to those observed in bulk electrodes. However, because of the size quantization and the distinctive electrode geometry, striking new effects are found.
