The rapid development of synthesis of noble metal nanoparticles over the last 10-15 years has given a broad arsenal of opportunities to the scientists, beginning from the well-known nanoparticles, 'nanoclouds', 'nanospheres', 'nanostars', 'nanonecklaces', 'nanorods', nanowires', 'nanosensors', 'nanochips', 'nanocells'. The unique nanoparticle properties have expanded their applications in a wide range of fields such as chemistry, physics, medicine, material science, biology, etc. Nanoparticles of gold, platinum and silver have found applications in electronics, catalysis and ceramics, in pharmacy, in the production of polymers with better properties, in optics and others. The resonance optical properties of nanoparticles, along with the high specificity of biomolecular recognition, have opened a new avenue for applications in biomedical diagnostics, targeted drug delivery, optical imaging and photothermal therapy of cancer cells in vitro.
The analysis of literature survey has shown that the major contemporary research directions are on the development of new methodologies for synthesis of nanocrystal structures having definite sizes and shapes. Multitude experimental works on synthesis of noble metal nanopatricles have been proposed. The properties of nanoparticles depend on many controllable, variable parameters. The use of a control of a synthesis of nanoparticles of noble metals having engineered properties is determined by the strong influence of their size, shape, structure and aggregates on their physical chemical properties as well as on their resonance and spectral characteristics.
