Microfluidic Methods in Janus Particle Synthesis
Summary
This review examines microfluidic-based methods for synthesizing Janus particles -- asymmetric particles with two distinct surface chemistries -- highlighting how these techniques offer superior control over reaction conditions, rapid prototyping, and low reagent consumption compared to conventional synthesis methods.
Janus particles have been at the center of attention over the years due to their asymmetric nature that makes them superior in many ways to conventional monophase particles. Several techniques have been reported for the synthesis of Janus particles; however, microfluidic-based techniques are by far the most popular due to their versatility, rapid prototyping, low reagent consumption and superior control over reaction conditions. In this review, we will go through microfluidic-based Janus particle synthesis techniques and highlight how recent advances have led to complex functionalities being imparted to the Janus particles.
