Effects of the microchannel shape upon droplet formations during synthesis of nanoparticles

Abstract

Advances in nanotechnology have made it possible to produce minimal tools and equipment that can be used to control tiny volumes of fluids. Currently, at the center of attention of scientists in various fields, such systems are referred to as microfluidic systems. Also, the ability to synthesize nanoparticles with precise control over the particle's form and size is crucial. The primary goal of this research was to see if the nozzle-focused microchannels could have been used to synthesize the Polycaprolactone (PCL) polymer nanoparticles through the COMSOL Multiphysics 5.4 software medium. In this study, the velocity and static pressure of the droplet after leaving the nozzle and entering the main channel, as well as the size, shape, distribution, and weight of the droplet in terms of the time step, were understudied. It was revealed that the channel's design allowed the droplets to keep their steady structure at its conclusion. Finally, it was shown that the droplet possessed a dual functionality of place and time in terms of size and weight distribution after a time step of 0.00305 seconds. The maximum drop saturation mass was formed, and the droplet diameter size displayed a plateau after 0.01 seconds.
