Advances in dielectric elastomers for actuators and artificial muscles

A number of materials have been explored for their use as artificial muscles. Among these, dielectric elastomers (DEs) appear to provide the best combination of properties for true muscle-like actuation. DEs behave as compliant capacitors, expanding in area and shrinking in thickness when a voltage is applied. Materials combining very high energy densities, strains, and efficiencies have been k...

Using metallo-supramolecular block copolymers for the synthesis of higher order nanostructured assemblies

Many research groups have explored the properties and solution self-assembly of main chain metallo-supramolecular multiblock copolymers. Until recently, these metal complexes have been used to prepare mainly micelle type structures. However, the self-assembly of such copolymers has been exploited further to create more advanced architectures which utilize the reversible supramolecular linkage o...

Effect of Gold Nanoparticles on the Thermosensitivity, Morphology, and Optical Properties of Poly(acrylamide-acrylic acid) Microgels

Novel positive thermosensitive microgels of poly(acrylamide-acrylic acid) with embedded gold nanoparticles have been synthesized and characterized by means of dynamic light scattering, UV-vis spectroscopy, field emission scanning electron microscopy, and transmission electron microscopy. These systems show temperature (upper critical solution temperature-like volume phase transition) and optica...

Single-step electrospinning of bimodal fiber meshes for ease of cellular infiltration : Single-Step Electrospinning of Bimodal Fiber Meshes …

Bimodal fiber meshes with fiber diameters differing by one order of magnitude, are electrospun in a simple one-step process, using a standard single syringe electrospin setup. The nano- and microfiber meshes combine the benefits of nanofibers (cell adhesion, proliferation) with those of microfibers (open structure, large pore size) and are therefore interesting as scaffolds for cellular infiltr...

Morphology and pH Sensing Characteristics of New Luminescent Electrospun Fibers Prepared from Poly(phenylquinoline)-block-Polystyrene/Polystyrene Blends : Morphology and pH Sensing Characteristics of New Luminescent Electrospun …

New luminescent electrospun (ES) fibers for pH-tunable colorimetric sensors were prepared from binary blends of poly(phenylquinoline)-block-polystyrene (PPQ-b-PS)/polystyrene (PS) with a single-capillary spinneret. The PPQ-b-PS aggregated domain sizes in the ES fibers prepared from dichloromethane (CH(2) Cl(2) ), chlorobenzene (CB) and chloroform (CHCl(3) ) were 1.5 ± 0.5, 2.2 ± 0.4 and 4.1 ± 1...

Immobilization of Candida antarctica lipase B on Polystyrene Nanoparticles : Immobilization of Candida antarctica lipase B on Polystyrene …

Polystyrene (PS) nanoparticles were prepared via a nanoprecipitation process. The influence of the pH of the buffer solution used during the immobilization process on the loading of Candida antarctica lipase B (Cal-B) and on the hydrolytic activity (hydrolysis of p-nitrophenyl acetate) of the immobilized Cal-B was studied. The pH of the buffer solution has no influence on enzyme loading, while ...

A Novel Type of Vesicles Based on Ionic and π-π Interactions : A Novel Type of Vesicles Based on Ionic …

Electrostatic self-assembly can be used to form supramolecular vesicles in aqueous solution. Vesicles consist of cationic G8 poly(amidoamine) dendrimers and the trivalent sulfonate dye Ar27. No classical amphiphiles are present but the interplay of electrostatics, π-π interaction and geometric factors influences the structure formation. Labeled guest molecules, both small molecules and peptides...

Self-Assembled Micelles Based on PEG-Polypeptide Hybrid Copolymers for Drug Delivery : Self-Assembled Micelles Based on PEG-Polypeptide Hybrid …

A series of amphiphilic poly(L-leucine)-block-poly(ethylene glycol)-block-poly(L-leucine) (PLL-PEG-PLL) hybrid triblock copolymers have been synthesized. All the blocks in this system have good biocompatibility and low toxicity. The PLL-PEG-PLL copolymers could self-assemble into micelles with PLL blocks as the hydrophobic core and PEG blocks as the hydrophilic shell, which were characterized b...

Fluorinated copolymer nanoparticles for multimodal imaging applications

Nanomaterials have emerged as valuable tools in biomedical imaging techniques. Here, the synthesis and characterization of a novel fluorinated nanoparticle with potential applications as an MRI contrast agent is reported. Particles were synthesized using a free radical polymerization technique. Secondary ion mass spectrometry analysis showed that the particles' surface contained fluorinated gro...
