Energy Transfer in Silica Nanoparticles: An Essential Tool for the Amplification of the Fluorescence Signal
The careful design of dye doped silica nanoparticles in order to induce controllable energy transfer processes can yield very sophisticated species able to perform precious and complex functions. They can be therefore exploited in many fields of great economical and social importance, such as medical diagnostics, molecular biology, and solar energy conversion. In this chapter, we present the characterization of some functionalized silica nanoparticles with a particular emphasis on the discussion of the the energy transfer processes at the basis of their properties. Since a careful design is fundamental in the realization of more and more sophisticated materials, we also discuss the synthesis of these systems, in order to suggest new routes for the preparation of such valuable and versatile objects.
