This study demonstrates a new method for the synthesis of organic-inorganic hybrid particles composed of inorganic silica shell and organic core particles. The organic core particle is prepared with a uniform size using droplet-based microfluidic technology. In the process of preparing the organic core particles, the uniform droplets are generated by independently controlling the flow rates of the dispersed phase containing photocurable resins and the continuous phase. After the generation of droplets in the microfluidic device, the droplets are photo-polymerized as particles by ultraviolet irradiation at the ends of the microfluidic channels. The core particle is coated with the nano complex composed of polyallylamine hydrochloride (PAH) and phosphate ion (Pi) through strong non-covalent interaction such as hydrogen bonding and electrostatic interaction under optimized pH conditions.
