A flow-type nanoparticle generation system using a microchannel device for generating and quenching droplets

High quality nanoparticles have been required in many industrial fields. By a principle of re-crystallization process, nanoparticles can be formed by quenching a solution. Thus, the quenching of micro droplets is effective for nanoparticle generation. In this study, we have developed a flow-type system for nanoparticles generation. In the system, generated micro droplets are quenched in continuous phase with small thermal conductivity using a microchannel device. We have successfully maintained the temperature of droplets before the quenching process and obtained fine nanoparticles.
