“…4C enabled the synthesis of polymeric NPs via droplet-based microfluidics. 72 The polymers hyaluronic acid (HA) and linear polyethyleneimine (LEPI) were covalently crosslinked in each droplet to produce highly monodisperse polymeric NPs with tunable sizes of 92-190 nm and a very small PDI of 0.015. The release of encapsulated DOX exhibited an enhanced antiblastic effect even at sublethal dosages, highlighting the applicability of this droplet-based microfluidic method in nanomedicine scenarios.…”

Droplet-based microfluidics offer great opportunities for applications in various fields, such as diagnostics, food sciences, and drug discovery. A droplet provides an isolated environment for performing a single reaction within a microscale-volume sample, allowing for a fast reaction with a high sensitivity, high throughput, and low risk of cross-contamination. Owing to several remarkable features, droplet-based microfluidic techniques have been intensively studied. In this review, we discuss the impact of droplet microfluidics, particularly focusing on drug screening and development. In addition, we surveyed various methods of device fabrication and droplet generation/manipulation. We further highlight some promising studies covering drug synthesis and delivery that were updated within the last 5 years. This review provides researchers with a quick guide that includes the most up-to-date and relevant information on the latest scientific findings on the development of droplet-based microfluidics in the pharmaceutical field.

Microdroplets have been widely used in different fields due to their unique properties, such as compartmentalization, single-molecule sensitivity, chemical and biological compatibility, and high throughput. Compared to intricate and labor-intensive microfluidic techniques, the centrifuge-based method is more convenient and cost-effective for generating droplets. In this study, we developed a handy injection molding based method to readily produce monodisperse droplets by centrifugation. Briefly, we used two three-dimensional (3D) printed master molds with internal cavities to forge two coupled sub-molds by injecting polydimethylsiloxane (PDMS) and casted these two PDMS sub-molds into a nested structure that clamps the micro-channel array (MiCA) by injecting polyurethane resin. This method enables the generation of various sizes of monodispersed microdroplets by centrifugation with proper parameters within 10 min. To assess the performance of this method, homogeneous fluorescent hydrogel microspheres were generated and droplet digital polymerase chain reaction (ddPCR) was carried out. Overall, this method offers high-throughput droplet generation, reduces costs compared to other methods, and is user-friendly.
