“…Consequently, a mixture of an aqueous phase with an oil phase generates only oil droplets, as shown in Figure 2 . This configuration might also have important applications in the synthesis of hydrophobic nanoparticles [ 57 , 58 ]. In general, the synthesis of hydrophobic nanoparticles can be performed either in the aqueous system, functionalized in the next step to obtain hydrophobic nature [ 59 ], or directly in the organic phase [ 60 ].…”

In this paper, micro droplets are generated in a microfluidic focusing contactor and then they move sequentially in a free-flowing mode (no wall contact). For this purpose, two different micro-flow glass devices (hydrophobic and hydrophilic) were used. During the study, the influence of the flow rate of the water phase and the oil phase on the droplet size and size distribution was investigated. Moreover, the influence of the oil phase viscosity on the droplet size was analyzed. It was found that the size and size distribution of the droplets can be controlled simply by the aqueous phase flow rate. Additionally, 2D simulations to determine the droplet size were performed and compared with the experiment.

“…If the phase to be dispersed is “pressed” through the small holes of the plate, by virtue of the shear force, a large number of droplets (one per hole) is released in a continuous manner (Figure ). Alternatively, emulsion polymerization can be performed using highly efficient micromixers or with the aid of ultrasounds …”

“…During the last decade, significant scientific efforts have been devoted to the study of heterogeneous polymerization in microstructured devices. The main topic of the studies has been suspension polymerization, for the synthesis of both highly monodisperse and multifunctional particles, i.e., Janus‐particles, core–shell particles, multicore particles, nonspherical particles, and also for scale‐out, commonly done via a numbering‐up of the microfluidic systems employed . The latter context is particularly relevant, because it shows that these efforts were not only restricted to the development of devices for lab experimentation but were also aimed to commercial production scale.…”

Polymeric micro‐ and nanoparticles receive the attention of researchers in different areas such as drug delivery, sensing, imaging, cosmetics, diagnostics, and biotechnology. However, processes with conventional equipment do not always allow precise control of their morphology, size, size distribution, and composition. On the other hand, microreaction technology offers improved control over the hydrodynamics, mass and heat transfer, allowing production of polymeric particles with better defined or new characteristics. Thus new horizons in polymer particle engineering arise from the use of microstructured or microfluidic devices. This article gives an insight into the latest developments and trends in the production of polymeric micro‐ and nanoparticles realized by microreaction technology directly.

“…[11][12][13][14] The homogeneity of particles depends on the homogeneity of the initiator reaction and the spatial distribution of monomer and initiator. This process has been well known as large-scale batch process for a long time, but it can also be realized in a microcontinuous flow.…”
