Firstly, I would like to express my special appreciations and thanks to my supervisor, Dr. Lucas Waltzer, who has been a tremendous mentor for me. Thank you for adopting me into CBD family and for continuous patience and support on both my research and my life in France. Your guidance helped me a lot all the time in research work and this thesis writing. Besides my supervisor, I would like to thank my co-supervisor, Dr. Marc Haenlin, for his support and enthusiasm and the rest of my thesis committee members, Prof. Christiane Bierkamp, Dr. Bruno Lemaitre, Dr. Marie-Bérengere Troadec, Dr. Magalie Lecourtois and Dr. Anne Plessis for their insightful comments and encouragement, but also for making my defense be an enjoyable moment and hard questions which incented me to widen my research horizon. My sincere thanks also go to Dr. Vanessa Gobert, Dr. Fernando Roch, Dr. Billel Benmimoun, Dr. Marion Miller and our technician Benoir Augé and Sandra Bernat-Fabre, those who taught me how to perform experiments, how to analyze experimental data, how to use various scientific instruments as well as always answer my questions kindly and patiently. I also would like to thank my two Chinese colleagues, Dr. Qiongyue Xu and Lu Wei, at the lab, who helped me a lot when I had a hard time and made me feel like at home when I felt lonely. Last but not the least, I would like to thank my family. Any words cannot express how grateful I am to my mother and my father, for all of the sacrifices that they have made on my behalf and for supporting me spiritually all the time. i ii Contents Acknowledgements ................................................................................................................. i Abstract .................................................................................................................................. v Résumé ................................................................................................................................. vii Foreword ............................................................................................................................. ixx List of abbreviations ............................................................................................................ xii List of figures ....................................................................................................................... xv List of tables ....................................................................................................................... xvii Chapter I Introduction ....................................................................................................... 1 1.
