Confinement and guiding of light energy at nanoscale in devices composed of colloidal building blocks, requires a precise control of (i) the morphology of the nanoparticles, (ii) their spatial organization into larger scale architectures and (iii) the coupling between plasmonic colloid and optically active. This thesis work explores new synthetic approaches, including bio-inspired ones, of these three challenges.As a first insight, we have employed biomineralization principles to tune the plasmon-fluorophore coupling in order tocontrol the fluorescence enhancement. The fluorescence properties of a well-organized, finite ensemble of porphyrins called J-aggregates is modulated by the templated encapsulation of silica of controlled thickness, ...
