Flexible responsive Janus nanosheets.
Flexible Janus nanosheets of molecular scale thickness (3.5 nm) are massively fabricated by a sol-gel process of a self-assembled monolayer of an amphiphilic silane onto a template. Groups of both sides are tuneable, and thus performance of the nanosheets, for example, is pH responsive. As a flexible solid emulsifier, the desired species can be wrapped with an individual nanosheet, which is pH ...
متن کاملA Novel Composite Membrane for pH Responsive Permeation
Objective(s) In this study, a kind of pH sensitive composite membrane was prepared and drug permeation through it was investigated in terms of pH. Rationale of this study originated from the fact that a pH change which may be a result of a disease state in the body can trigger drug release. Materials and Methods Here, a kind of pH sensitive composite membrane containing different nanoparticle ...
متن کاملReconfigurable responsive structures assembled from magnetic Janus particles†‡
Responsive materials are used in many diverse applications including actuators, sensors, tunable viscosity liquids, and displays. In addition to materials with controlled properties, a number of ‘‘smart’’ building blocks are promising as components of responsive assemblies. Electroand magnetorheological fluids rely on such assemblies for their dynamic change in viscosity. The design of building...
متن کاملCompartment fabrication of magneto-responsive Janus microrod particles.
Monodispersed magneto-responsive microrod particles of variable magnetic/non-magnetic ratios and chemical compositions are created by compartment fabrication in a single poly(dimethylsiloxane) (PDMS) mold with periodic hole arrays. By labeling the two ends with green and red fluorescent dyes separately, we show that the particles can flip freely and reversibly in a confined geometry under the m...
متن کاملReversible Janus particle assembly via responsive host-guest interactions.
Reversible assembly of Janus particles was manipulated by host-guest interaction of β-cyclodextrin (β-CD) and azobenzene. One side of every Janus particle was modified with β-CD. Superstructures of Janus particles were formed by adding azobenzene-containing polymers to the dispersion of Janus particles. The superstructures were reversibly disassembled by adding α-CD or light irradiation.
