Self-optimizing parallel millifluidic reactor for scaling nanoparticle synthesis.

We developed a 16-channel millifluidic reactor that uses a multiphase gas-liquid flow to continuously produce colloidal CsPbBr3 quantum dots with a throughtput of similar to 1 L h(-1). The optical properties of the product were monitored, and the reaction conditions were optimized in real time based on the in situ photoluminescence characteristics of the quantum dots.
