Structure of strongly interacting polyelectrolyte diblock copolymer micelles.
The structure of spherical micelles of the diblock poly(styrene-block-acrylic acid) [PS-b-PA] copolymer in water was investigated up to concentrations where the polyelectrolyte coronal layers have to shrink and/or interpenetrate in order to accommodate the micelles in the increasingly crowded volume. We obtained the partial structure factors pertaining to the core and corona density correlation...
متن کاملHollow flower micelles from a diblock copolymer.
A poly(2-vinylpyridine)-block-poly(2-(4-vinylphenyl)pyridine) (P2VP106-b-PVPPy95) coil-coil diblock copolymer forms hollow flower micelles in a mixed solvent of methanol and water (95/5, v/v) in a one step process. The geometry and composition of the micelles allow formation of a Pt-Au bimetallic dendritic nanocatalyst with a Pt leaf at room temperature.
متن کاملSupracolloidal polymer chains of diblock copolymer micelles.
Directional attraction with lateral repulsion between colloidal nanoparticles can create their supracolloidal chains. Here, we demonstrate supracolloidal polymers of diblock copolymer micelles, which were polymerized by adjusting the polarity of the solvent. We also synthesized supracolloidal random and block copolymer chains.
متن کاملPrediction of solvent-induced morphological changes of polyelectrolyte diblock copolymer micelles.
Self-assembly processes of polyelectrolyte block copolymers are ubiquitous in industrial and biological processes; understanding their physical properties can also provide insights into the design of polyelectrolyte materials with novel and tailored properties. Here, we report systematic analysis on how the ionic strength of the solvent and the length of the polyelectrolyte block affect the sel...
متن کاملEncapsulation of Curcumin in Diblock Copolymer Micelles for Cancer Therapy
Application of nanoparticles has recently promising results for water insoluble agents like curcumin. In this study, we synthesized polymeric nanoparticle-curcumin (PNPC) and then showed its efficiency, drug loading, stability, and safety. Therapeutic effects of PNPC were also assessed on two cell lines and in an animal model of breast cancer. PNPC remarkably suppressed mammary and hepatocellul...
