Introduction to Polymer Microparticle

Polymer microparticles are a group of biomaterials with sizes from 1 to 1000 µm. Polymer microparticles have been treated as a drug delivery strategy and are broadly used in many therapeutic applications. Polymer microparticles do not need to be removed from the body, with high stability and high reproducibility, making them a powerful tool for the development of hydrophilic and hydrophobic drugs. Moreover, recent reports have revealed that polymer microparticles can regulate long-time drug release rates and reduce drug toxicity. Before determining suitable methods for the synthesis of polymer microparticles, an understanding of the drug properties, such as solubility, biocompatibility, as well as crystallinity, is necessary.

In general, the conventional microemulsion method provides a unique opportunity to prepare polymer microparticles with suitable size and perfect internal structure. Among them, the single emulsion is a type of the oil/water (o/w) or water/oil (W/O) emulsion method for the production of solid particles, which usually have a polymer core, in favor of coating hydrophobic drugs. In addition, hydrophilic drugs, like proteins, are usually encapsulated in water/oil/water (w/o/w) double emulsions because they produce core-shell microparticles with hydrophilic encapsulation characteristics. However, numerous data have indicated that this method can lead to an increase in particle size and a decrease in drug loading rate. As a consequence, there is an urgent need to develop other attractive strategies to engineer, synthesize, and produce new polymer microparticles in different clinical practices.

Microfluidic Solutions for Polymer Microparticle

In recent years, microfluidic technology has been regarded as a key way of synthesizing polymer microparticles. This technique can produce droplets or particles in a device that is supplied with a polymer and a drug containing an immiscible solution. In this condition, droplets can be solidified through polymerization or solvent evaporation. Microfluidics allows the generation of a large number of polymer microparticles with predictable size and better stability, which provides support data in the synthesis of various polymer microparticles loaded with candidate drugs of biomedical interest. For example, it has been described that the activity of polymeric microparticles loaded with small molecule drugs has been evaluated in C6 glial cells of a mice tumor model. The data have suggested that an appropriate route of drug administration loaded in polymeric microparticles can achieve continuous release of the drug and decrease its potential side effect on patients.
