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

Janus Particles in a Nonpolar Solvent
Langmuir, 2016Amphiphilic 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 with Varying Configurations for Emulsion Stabilization
Industrial & Engineering Chemistry Research, 2019Analogous to molecular surfactants, amphiphilic Janus particles can function as surface active agents to stabilize emulsions. For molecular surfactants, the shape and amphiphilicity, described by packing parameters and hydrophilic–lipophilic balance (HLB)

Biphasic Janus particles with nanoscale anisotropy
Nature Materials, 2005Advances 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

Interactions between Janus particles and membranes
Nanoscale, 2012Understanding how nanoparticles interact with cell membranes is of great importance in drug/gene delivery. In this paper, we investigate the interactions between Janus particles and membranes by using dissipative particle dynamics, and find that there exist two different modes (i.e., insertion and engulfment) in the Janus particle-membrane interactions.

Janus balance of amphiphilic colloidal particles
The Journal of Chemical Physics, 2007We introduce the notion of “Janus balance” (J), defined as the dimensionless ratio of work to transfer an amphiphilic colloidal particle (a “Janus particle”) from the oil-water interface into the oil phase, normalized by the work needed to move it into the water phase.

Janus Particles at Liquid−Liquid Interfaces
Langmuir, 2006Following recent theoretical predictions, we report on the first experiments on the interfacial activity of so-called Janus nanoparticles (i.e., bifacial particles consisting of a gold and an iron oxide moiety). Using pendant drop tensiometry, we show that the amphiphilicity derived from the Janus character of the particles leads to a significantly ...

Triblock Janus Particles by Seeded Emulsion Polymerization
Macromolecules, 2019Triblock Janus particles are prepared by two-step seeded emulsion polymerization against eccentric polymer hollow particles. Two silica bulges are sequentially grown at the eccentric zone transiting from the thick shell to the thin shell.
