Multiple-Sized Amphiphilic Janus Gold Nanoparticles by Ligand Exchange at Toluene/Water Interface
Amphiphilic Janus gold nanoparticles (GNPs) are prospected to encapsulate drug molecules in cancer therapy and to serve as heterogeneous catalysts at oil/water interfaces, where Janus GNPs with different sizes are required. In this work, multiple-sized precursor GNPs were synthesized by seeded growth method protected with tris(hydroxymethyl)phosphine oxide (THPO) ligand molecule, and a ligand ex...

Solvents induce phase separation for fabrication of Janus hybrid nanoparticles: A dissipative particle dynamics simulation
Polyacrylic acid-gold (PAA-Au) Janus nanoparticles (JNPs) show a broad application prospect in many fields. However, PAA-Au JNPs are difficult to prepare and characterize due to their specific structures and properties. In this work, the self-assembly of PAA-Au NPs was investigated by dissipative particle dynamics (DPD) simulation method. It was found that PAA-Au NPs had a structure transition wit...

Tuning Metamaterials Nanostructure of Janus Gold Nanoparticle Film for Surface-Enhanced Raman Scattering
Large-area metamaterial nanostructures of a Janus gold nanoparticle (AuNP) film decorated with thiol-terminated polymers have been fabricated and tuned at an oil/water interface by a facile and innovative process. The results show that AuNPs had been arrayed with ultrasmall gaps between neighboring particles laminated with polymer which is called a Janus film. This film exhibits a sensitive proper...

【ACS Appl. Mater. Interfaces】Janus Polymer/Carbon Nanotube Hybrid Membranes for Oil/Water Separation
A robust and simple method is provided to fabricate Janus polymer/carbon
nanotube (CNT) hybrid membranes for oil/water separation. Starting from CNT
membranes formed by dispensing, hydrophobic poly(styrene) (PS) and hydrophilic
poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) were grated from different
sides of the photoactive CNT membranes via self-initiated photografting and

Single Emulsion Microfluidic Production of Janus and Core-Shell Particles via Off-chip Polymerization
In this work, we describe a straightforward approach to produce monodisperse Janus and core-shell particles by using organic solvent free single emulsion droplet-based microfluidic device combining with off-chip polymerization. To accomplish this, methyl methacrylate (MMA) was used as both the oil phase and solvent to dissolve a polymerizable PEG-based macromolecular surfactant, instead of t...

A Supramolecular Janus Hyperbranched Polymer and Its Photoresponsive Self-Assembly of Vesicles with Narrow Size Distribution
Herein, we report a novel Janus
particle and supramolecular block copolymer consisting of two chemically
distinct hyperbranched polymers, which is coined as Janus hyperbranched polymer.
It is constructed by the noncovalent coupling between a hydrophobic
hyperbranched poly(3-ethyl-3-oxetanemethanol) with an apex of an azobenzene
(AZO) group and a hydrophilic hyperbranched polyglycerol w...

Facile fabrication of Fe3O4@ PS/PGMA magnetic Janus particles via organic-inorganic dual phase separation
In this study, a facile strategy is developed to fabricate Fe3O4@polystyrene/poly (glycidyl methacrylate) (Fe3O4@PS/PGMA) magnetic Janus particles (MJPs) by solvent evaporation-induced organic–inorganic dual phase separation. The Fe3O4 nanoparticles (MNPs) are selectively dispersed on one side of the particles. The experimental factors on the morphology of Fe3O4@PS/PGMA MJPs, including the...
