Recent advances in the microfluidic production of functional microcapsules by multiple-emulsion templating

Abstract

Multiple-emulsion drops have served as versatile templates to design functional microcapsules due to their core-shell geometry and multiple compartments. Microfluidics has been used for the elaborate production of multiple-emulsion drops...

Designing photonic microparticles with droplet microfluidics

“…Nevertheless, various microfluidic techniques have recently been developed to increase the production throughput of monodisperse singleand multiple-emulsion drops. 126,127 Therefore, it is potentially possible to enhance the production throughput of photonic microparticles and ultimately achieve commercial-scale production. Another challenge is to reduce the size of photonic This journal is © The Royal Society of Chemistry 2022 microparticles.…”

“…Microfluidic technology has provided the controlled production of double-emulsion drops through two-step or single-step emulsification. 126,127 As the LC phases are insoluble in water, either the W/O/W or O/W/O composition can be used. W/O/W double-emulsion drops provide CLC shells.…”

Progress in the application of sustained-release drug microspheres in tissue engineering

“…There are four main methods for the preparation of droplets via passive methods: the flow focused, co-flow, T-junction and step junction methods ( Fig. 1 B) [ 44 ].…”

A novel insulin delivery system by β cells encapsulated in microcapsules

“…Various functional microcapsules have been developed by different technological applications, such as microfluidics, spray drying, and interfacial polymerization ( Chen et al, 2019 ). Among them, microfluidics is a well-known strategy for rapidly preparing microcapsules with the desired morphology ( Kim et al, 2022 ). The obtained microcapsules can effectively encapsulate the cells, but the cell viability in them is usually not adequate because the hydrogel shell reduces cell viability and intercellular communication and the compact shell restricts the internal cells from accessing external nutrients and limits insulin exiting the enclosure ( Khanmohammadi et al, 2020 ; Liu et al, 2021 ; Kim et al, 2022 ).…”
