Biological catalysis

One of the most important objectives of nanoscience and nanotechnology is to take advantage of the unique properties of nanomaterials. Nanomaterials can be synthesized from the assembly of individual Au NPs to give more or less ordered nanostructures possessing one-, two- or three-dimensional architectures. As described in the final section of this chapter, these Au nanomaterials can be applied in different fields such as optics, electronics, sensing, catalysis, biology-related applications, and so on. 

This chapter is concerned with dyes and pigments which are complexes of azo, formazan, azomethine, nitroso, anthraquinone and phthalocyanine ligands. Many of these compounds find important applications in other fields, particularly colour photography and reprography, analysis, catalysis, biology, and some modem high technology industries such as electronics. These applications are described in other chapters of this volume.

In this chapter, we have tried to carry out the restatement of the magnetic properties of fine particles resulting from the relaxation of their magnetic moments from theoretical as well as experimental points of view. We discussed the models, several with some details, that allow one to calculate the relaxation time of the particle magnetic moment, to evaluate the effect of the interparticle interactions, and to interpret the experimental results. We clearly stated our objections, without use of indirect sentences understandable only by specialists, because fine-particle studies can be of interest in various fields, for example, catalysis, biology, mineralogy. Of course, this is our opinion at the present time.
