Nanoparticles nanowires

In general, the various synthesis strategies for nanocarbon hybrids can be categorized as ex situ and in situ techniques [3]. The ex situ ( building block ) approach involves the separate synthesis of the two components prior to their hybridization. One can rely on a plethora of scientific work to ensure good control of the component s dimensions (i.e. size, number of layers), morphology (i.e. spherical nanoparticles, nanowires) and functionalization. The components are then hybridized through covalent, noncovalent or electrostatic interactions. In contrast, the in situ approach is a one-step process that involves the synthesis of one of the components in the pres-... 

The above sections should clearly demonstrate that the study of graphene and its hybrids, especially the latter, has only just begun. Hybrids of graphene with various inorganic nanostructures (nanoparticles, nanowires and nanosheets) are likely to possess many novel properties with potential applications. Graphene-MOF hybrids are yet to be explored extensively and they are found to reveal many useful properties. 

Nucleic acids can be conjugated to nano-objects, such as nanoparticles, nanowires, or nanotubes. The resulting nucleic acids-nano-objects hybrids combine the tailored recognition and catalytic properties of the nucleic acids with the electronic, optical, and catalytic features of the nano-objects. The forthcoming chapter will address the organization of nanoscale supramolecular structures of nucleic acids on... 

It has been well known that HRTEM is a powerful tool to investigate structures of low-dimensional oxides, such as nanoparticles, nanowires, nanorods and nanotubes, while the information from powder dilfraction of these low-dimensional materials is normally very Hmited merely because their small crystaUite sizes. For the nanoscale oxides, HRTEM can give useful information on particle size, crystal structure, particle morphology, structural defects and possible inter-particle connections. 

The synthesis of nanomaterials and assembling the nanostructures into ordered arrays to render them functional and operational are crucial aspects of nanoscience. The materials/structures include nanoparticles, nanowires, nanotubes. 

Although different nanomaterials such as nanoparticles, nanowires and nanotubes are used for the construction of biosensor, this chapter is mainly devoted to the use of AuNPs for the construction of electrochemical biosensor and their analytical performances. Further, in this chapter we restrict ourselves in the electrochemical sensing of glucose, ascorbic acid, uric acid and dopamine derivatives using the AuNPs modified electrodes.

A number of basic electrochemical research works related to nitrate ion reduction have been reported in the last two decades, hi most studies, the authors attempt to reduce the overpotential and increase the current for nitrate reduction by synthesizing materials with functimial compositirMis (e.g. alloys, monocrystals, etc.) and highly reactive surfaces (nanoparticles, nanowires, porous materials, etc.).
