Silica Nanoparticle Formation by Using Droplet-Based Microreactor

Abstract

This paper describes a method for the synthesis of silica nanoparticles that can be later used for coating of quantum dots inside a microfluidic reactor. Here, a droplet-based system is used where two reagents were mixed inside the droplets to obtain silica. Particles in the size range of 25±2.7 nm were obtained with comparable size distribution to controlled batchwise synthesis methods. This method is suitable to be used later to coat CdSe nanoparticles inside the microreactor.
