WebAbstract: A synthesis of gold nanoparticles (GNPs) dispersion in an organic solvent by a glass microfluidic device was reported in this paper. Brust-Schiffrin synthesis method can prepare GNPs dispersion in toluene. However, since the method is a complex synthesis process such as mixing and separation, control of nanoparticle size was difficult.
