Conelike Janus Composite Particles
Macromolecules, 2015Conelike cross-linked PS particles are polymerized at a patchy emulsion interface. The PS particles synthesized in the dispersed paraffin phase immigrate toward the interface due to the Pickering effect. At the triple phase contact line, the particles are squeezed into cone shape under an outward convex interfacial tension mismatch.

Macrophage Uptake of Janus Particles Depends upon Janus Balance
Langmuir, 2015Properties 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, 2015Crescent-to-moon shaped anisotropic particles in both micrometer and nanometer size have been successfully fabricated in batch scale with Janus emulsion as template.

Janus Particles Templated by Janus Emulsions and Application as a Pickering Emulsifier
Langmuir, 2017One-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.

Scattering behaviour of Janus particles [PDF]
Applied Physics A: Materials Science & Processing, 2002 Recent advances in polymer synthesis has produced so-called Janus micelles: tailor-made copolymer structures in which the blocks constitute separate moieties. We present expressions for the form factors, P(Q), and the radii of gyration, Rg, of Janus particles with spherical and cylindrical morphology and check their validity by comparison to simulated ...

Janus Balance and Emulsions Stabilized by Janus Particles
2012Janus particle-stabilized emulsions share the characteristics of both emulsions stabilized by surfactant molecules and emulsions stabilized by homogeneous particles. On the one hand, Janus amphiphilic particles can be viewed as the colloidal version of small amphiphilic molecules, and much can be le...

Janus Particle Synthesis, Assembly, and Application
Langmuir, 2017Janus particles are colloidal particles with more than a single type of surface chemistry or composition, ranging in size from hundreds of nanometers to a few micrometers. Like traditional colloids, they are large enough to be observed under optical microscopy in real time and small enough to diffuse by Brownian motion, but their interesting and useful

Bipolar Janus particle assembly in microdevice
ELECTROPHORESIS, 2015In 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.

Adsorption of Janus particles to curved interfaces
The Journal of Chemical Physics, 2007We investigate the adsorption of a spherical Janus particle to a spherically curved liquid-liquid interface. We show that the equilibrium contact angle is determined by the geometry of the particle, its wettability, and also the interfacial curvature.

Janus molecularly imprinted polymer particles
Chem. Commun., 2014Janus MIP particles were synthesized via a wax–water Pickering emulsion. The MIP microtransporter concept provided the Janus MIP particles with attractive capabilities for autonomous binding and controlled drug delivery.
