Title: Exploring the Factors Influencing the Plasmon-Enhanced Production of Singlet Oxygen by Developing Model Hybrid Photosensitizer-Metal Nanoparticles
Mr. Macia’s thesis summarizes his research work in the field of plasmonic enhancement of singlet oxygen. Up to date, the field of plasmonic was focused on limited applications such as enhancement of fluorescence. Nicolas has broadened the scope of this field by engineering unique nanoparticles that amplify chemical reactions triggered by light. He has pioneered multiple series of nanoparticles composed of a plasmonic core and a photosensitizer located at a precise distance from the core. He was the first one to prove experimentally and quantify that the distance from the nanoparticles and their shape are two key parameters that impact singlet oxygen production. More importantly, he established the role of the far-field on the enhancement factor leading to the first set of guidelines that currently allows research to predict accurately the enhancement factor. He has also steered his research towards practical applications, proving engineered hybrid nanoparticles are very effective at killing a wide variety of bacterial strains.
Nicolas has written an exceptional thesis encompassing a unique body of work, which is not only highly original, but appeals to all readers, from the novice to the expert in the field. His outstanding expertise in the field of photochemistry has been central to the success of other projects, leading to his researching being published in chemistry flagship journals such at the Journal of The American Society, which best illustrates the impact, the quality and the originality of his work.
