Nanoparticle Preparation and Its Application — A Nanotechnology Particle Project in Japan

Nanoparticles such as metals, semiconductors and metal oxides are of great interest for a wide variety of applications in the field of information, energy, environmental and medical technologies due to their unique or improved properties determined primarily by size, composition and structure along with their self-organized film structures. In this presentation, Japan’s national project on nanoparticle synthesis and its applications in nanotechnology programs is reviewed along with some new findings on synthesis technologies and the related nanoparticle-based nano-structures developed during the project. The synthesis methods include liquid phase, gas phase, liquid-based gas phase such as novel spray methods and sol-gel assisted in-situ techniques and continuous mass production method.
