Janus Nanoparticles for Improved Dentin Bonding

ACS Applied Materials & Interfaces, 2018
The amphiphilic monomer 2-hydroxyethyl methacrylate (HEMA) is widely used in dental adhesives as a priming component, especially for dentin bonding. It behaves as a compatibilizer between hydrophilic and hydrophobic components and stabilizes the multicomponent adhesive system.

Lipid Bilayer Disruption by Amphiphilic Janus Nanoparticles: The Role of Janus Balance

Langmuir, 2018
Amphiphilic nanoparticles are known to cause defects in lipid bilayers. However, we have shown recently that their disruptive effects are significantly enhanced when surface charges and hydrophobic groups are spatially segregated on opposite hemispheres of a single particle. Using the same amphiphilic cationic/hydrophobic Janus particle system, here we

Janus Nanoparticles: From Fabrication to (Bio)Applications

ACS Nano, 2021
Janus nanoparticles (JNPs) refer to the integration of two or more chemically discrepant composites into one structure system. Studies into JNPs have been of significant interest due to their interesting characteristics stemming from their asymmetric structures, which can integrate different functional properties and perform more synergetic functions ...

Self-Assembly of Janus Nanoparticles in Diblock Copolymers

ACS Nano, 2010
Janus nanoparticles with two chemically different compartments have been shown to be a unique class of building blocks in solution. Here we perform mesoscale simulations to explore the self-assembly of Janus nanoparticles with widely varying architectures in diblock copolymers.

Rupture of Lipid Membranes Induced by Amphiphilic Janus Nanoparticles

ACS Nano, 2018
The surface coatings of nanoparticles determine their interaction with biomembranes, but studies have been limited almost exclusively to nanoparticles with a uniform surface chemistry.

The Janus Faces of Nanoparticles

Journal of Nanoscience and Nanotechnology, 2007
There is an paradox apparent in the fact that nanoparticles have potential use in nanomedicine for imaging and therapy, whereas combustion-derived NP are thought to be responsible for adverse health effects of air pollution. The nanotechnology industry is in the process of producing a number of new nanoparticles which are as-yet unquantified with ...

Chemotaxis of Active Janus Nanoparticles

Nano Letters, 2018
While colloids and molecules in solution exhibit passive Brownian motion, particles that are partially covered with a catalyst, which promotes the transformation of a fuel dissolved in the solution, can actively move. These active Janus particles are known as "chemical nanomotors" or self-propelling "swimmers" and have been realized with a range of ...

Bottlebrush-Colloid Janus Nanoparticles

ACS Macro Letters, 2019
A bottlebrush-colloid Janus nanoparticle (JNP) with a ball-and-stick structure is reported. A single poly(4-vinyl benzyl chloride) (PVBC) polymer chain was grafted onto the amine-capped Fe3O4@NH2 nanoparticle. pH-responsive 2-diethylaminoethyl methacrylate (DEAEMA) and water-soluble oligo(ethylene glycol) methacrylate (OEGMA) were sequentially grown ...

Controlled Assembly of Janus Nanoparticles

Langmuir, 2010
Janus nanoparticles were prepared by interfacial ligand exchange reactions of octanethiolate-protected gold (AuC8) nanoparticles with 3-mercapto-1,2-propanediol (MPD) at the air/water interface. AFM and TEM measurements showed that the resulting particles formed stable aggregates in water with dimensions up to a few hundred nanometers, in sharp ...
