Janus Particle Synthesis and Assembly

Advanced Materials, 2010
AbstractJanus particles, colloid‐sized particles with two regions of different surface chemical composition, possess energetic interactions that depend not only on their separation but also on their orientation. Research on Janus and colloidal particles that are chemically patchy in even more complicated fashion has opened a new chapter in the colloid ...

Multifunctional Superparamagnetic Janus Particles

Langmuir, 2009
In this study, we report the microfluidic-based synthesis of a multifunctional Janus hydrogel particle with anisotropic superparamagnetic properties and chemical composition for the bottom-up assembly of hydrogel superstructures. In a uniform magnetic field, the resulting Janus magnetic particles fabricated in the present method exhibit chainlike or ...

Synthesis of Biofunctional Janus Particles

Macromolecular Rapid Communications, 2015
Janus particles with anisotropic biofunctionalities are perfect models to mimic anisotropic architectures and directional interactions that occur in nature. It is therefore highly desirable to develop reliable and efficient methods to synthesize biofunctional Janus particles.

Janus Particles in a Nonpolar Solvent

Langmuir, 2016
Amphiphilic Janus particles are currently receiving great attention as "solid surfactants". Previous studies have introduced such particles with a variety of shapes and functions, but there has so far been a strong emphasis on water-dispersible particles that mimic the molecular surfactants soluble in polar solvents.

Janus Particles Templated by Janus Emulsions and Application as a Pickering Emulsifier

Langmuir, 2017
One-step vibrational mixing has afforded the batch-scale preparation of a Janus emulsion. The fabrication of Janus particles (JPs) templated by Janus emulsions was motivated by the topology and composition of the Janus droplets being highly tunable and controllable.

Macrophage Uptake of Janus Particles Depends upon Janus Balance

Langmuir, 2015
Properties of synthetic particles, such as size and shape, influence how immune cells uptake vaccine and drug carriers. Here, we explore the role of a new property, anisotropic presentation of ligands, in particle uptake by macrophage cells. We use micrometer-sized Janus particles that are partially coated with ligands and investigate how the ligand ...

Anisotropic particles templated by Janus emulsion

Chemical Communications, 2015
Crescent-to-moon shaped anisotropic particles in both micrometer and nanometer size have been successfully fabricated in batch scale with Janus emulsion as template.

Bipolar Janus particle assembly in microdevice

ELECTROPHORESIS, 2015
In recent years, there are significant interests in the manipulation of bipolar Janus particles. In this article, we investigate the transient behavior of the electro‐orientation process and particle–particle interaction of ellipsoidal bipolar Janus particles in the presence and absence of a DC electric field.

Biphasic Janus particles with nanoscale anisotropy

Nature Materials, 2005
Advances in the field of nanotechnology have fuelled the vision of future devices spawned from tiny functional components that are able to assemble according to a master blueprint. In this concept, the controlled distribution of matter or 'patchiness' is important for creating anisotropic building blocks and introduces an extra design parameter--beyond
