The aim of this thesis was to design, synthesize and characterize dye-doped silica nanoparticles (DDSNPs) to be used as chemosensors or labels in bioanalytical applications. DDSNPs represent one of the most versatile and useful components in nanomedicine displaying important features such as high colloid stability in water, low toxicity, one-pot inexpensive synthesis and tunable fluorescence emission. Starting from the one-pot and highly reproducible synthesis of “silica-core/PEG shell” DDSNPs based on the use of micelles of Pluronic F127, in which take place both hydrolysis and condensation of the silica precursor and of the dyes functionalized with a triethoxysilane group, we developed DDSNPs suitable for optical and optoacustic imaging, drug loading and chemical sensing obtaining very interesting results for the further development of nanomedicine.
