Fabrication of polymeric Janus particles by droplet microfluidics

Abstract

This review presents a short description of the polymeric Janus particles fabricated by droplet microfluidics.

Dynamically reconfigurable complex emulsions via tunable interfacial tensions

“…Consequently, emulsions are central components of medicine, food and performance materials. Complex emulsions, including multiple emulsions and Janus droplets which contain hemispheres of differing material, are of increasing importance 1 in pharmaceuticals and medical diagnostics 2 , in the fabrication of microparticles and capsules 3–5 for food 6 , in chemical separations 7 , in cosmetics 8 , and in dynamic optics 9 . Because complex emulsion properties and functions are related to the droplet geometry and composition, the development of rapid, simple fabrication approaches allowing precise control over the droplets’ physical and chemical characteristics is critical.…”

Donut-like hybrid latex comprising discrete thermoplastic lobe and thermosetting shell

“…Fabrication of polymeric or organic-inorganic Janus particles by droplet microfluidics appears to be the easiest approach owing to its continuous preparation fashion [10]. Additionally, Pickering emulsion method is a favorable alternative to elaborate compartmentalized colloids with controllable surface functionality [11].…”

Droplet Merging on a Lab-on-a-Chip Platform by Uniform Magnetic Fields

“…LoC applications of DMF require droplet manipulation in order to perform operations such as droplet merging, mixing, breakup, and sorting. Droplet manipulation on a LoC platform has been used for the synthesis of novel materials6 relevant to biosensing7, three-dimensional (3D) cell culture8, photonic crystals9, Janus structures10, anisotropic particles11, functional polymeric structures121314, controlled encapsulation for drug delivery15 and multidimensional optical barcoding16. Specifically, droplet merging and mixing on LoC platform has been used for a broad range of biomedical applications17 such as bioassays1819, biomaterials20, single cell analysis21, cell sorting2223, population transcriptomics24, disease detection25, and diagnostics26.…”
