The photochemical properties of various nanoassemblies discussed in this chapter highlight the ways in which the metal and semiconductor nanopartides interact with light. Furthermore, one can fine tune these responses by subjecting nano-stmctures to an externally applied electrochemical bias. The ability to functionalize these nanopartides with photoactive molecules has opened new avenues to utilize these nanoassemblies in light energy conversion and catalytic applications. By suitably modulating the fluorescence of the surface bound fluorophore these...

The formation of Ag triangular nanoprisms from spherical nanopartides in the presence of trisodium citrate and bis(p-sulfonatophenyl)phenylphosphine (BSPP) (dipotassium salt) with fluorescent light [245] has been described, as has that of Au nanoprisms [246]. 

AMP) (20), bridged through a hybridization of the (21)-nudeic acid-functionalized CdSe/ZnS QDs and the (22)-nucleic acid-functionalized Au nanopartides, led to QD-Au nanopartide aggregates in which the fluorescence of the QDs was quenched by the gold nanopartides (Figure 6.20a). In the presence of AMP, the aptamer-AMP...

The anti-adenosine monophosphate aptamer 20 bridges the CdSe QD functionalized with nucleic acid 21 and the nucleic acid 14-modifled with gold nanopartides to form the respective aggregate. 

Semiconductor nanopartides are of particular importance due to their optical properties. They act as quantum dots and can be applied as components in optically active materials, as optically active labels for biomolecules and cells and as components in miniaturized optoelectronic devices [16]. Compound semiconductor nanopartides can be prepared by liquid-phase processes. Several groups have investigated the preparation of CdSe partides. The fluorescence emission of these particles is strongly dependent on the particle size. The realization of well[Pg.783]
