Abstract
Apparatuses and methods for synthesizing nanoparticles are provided. Methods for synthesizing nanoparticles are provided comprising mixing at least two solutions comprising the components of the nanoparticles within a micromixer; exposing the resultant mixed, unreacted, azeotropic solution to ultrasound; and collecting the generated nanoparticles. Apparatuses are also provided for synthesizing nanoparticles comprising a micromixer in fluid connection with a continuous reactor comprising at least one inlet, at least one outlet, and an ultrasound horn oriented such that the acoustic energy is transferred to the fluid within the continuous reactor.
