Another application of Zinc oxide nanostructure is immobilization of uricace onto ZnO nanorod and fabrication a sensitive biosensor for uric acid detection [167], The biosensor successfully used for micromolar detection of uric acid in the presence serious interferences, glucose, ascorbic acid, and 1-cysteine. The apparent KM value for the uric acid biosensor is 0.238 mM, showing high affinity of the biosensor. Direct electron transfer of SOD at a physical vapor deposited zinc oxide nanoparticles surface was investigated [168], In comparison to SOD immobilized onto ZnO nanodisks [169], the electron transfer rate constant is small and a quasi- reversible electrochemical behavior observed. A novel...

The National Toxicology Program (NTP) has initiated efforts to examine a select representation of nanostructures - carbon nanotubes, fuUerenes, nanostructured titanium dioxide (1102), and zinc oxide (ZnO) particles used in sunscreens and bactericides, and quantum dots. 

Crystallization and reduction of sol-gel prepared zinc oxide films derived from zinc acetate by irradiation with an UV lamp (185 and 254 nm) was studied (Asakuma et al. 2003). UV irradiation induced the formation of hexagonal ZnO crystals from amorphous ZnO films preheated at 100 C, while irradiation of porous ZnO films preheated at 60 C led also to formation of metallic zinc. Composite ZnO/Cu and ZnO/Ag/Cu nanostructures were prepared via the photocatalytic reduction (wavelength 310-390 nm) of cuprous chloride and silver nitrate over the chemically prepared ZnO nanoparticles in aqueous solution (Shvalagin et al. 2004). Amorphous ZnO thin films were prepared... 

Hollow Magnetic Nanocrystals Hollow nanoscale stmctures were first obtained by Y. Yin during the sulfurization of cobalt nanocrystals at elevated temperatures [145]. This process was found to lead to the formation of hollow cobalt sulfide nanocrystals such that, depending on the size of the cobalt nanocrystals and the cobalt sulfur molar ratio, different stoichiometries of hollow cobalt sulfide could be obtained. Hollow nanostmctures are usually formed through the nanoscale Kirkendall effect, which is based on the difference in diffusion rates of two species, and results in an accumulation and condensation of vacancies [146]. This phenomenon was first observed by Kirkendall at the interface of copper and zinc in brass in 1947 [147]. As a typical example of the nano-Kirkendall effect, the controllable oxidation of iron nanoparticles by air can lead to the formation of hollow iron oxide nanostructures, as shown in Figure 3.137. During the course of metal nanoparticle oxidation, the outward diffusion of metal occurs much faster in... 

The morphology of these nanostructures strongly depends on the technique selected for the preparation and on the operating conditions. Figures reports, as an example, some of the morphologies that may be achieved for tin and zinc oxide. The most important features of these nanowires for chemical sensors are their high surface to volume ratio and their single crystalline nature confirmed by transmission microscopy.
