Rheology and structure of worm-like micelles
Although worm-like micelles have been studied for over 20 years, the diversity of macroscopic behavior and the potential analogy to polyelectrolytes has driven continued study. During the last year, development and application of more realistic scattering models has yielded a deeper understanding of micelle structure. Comprehensive studies on systematic systems are being reported that combine s...
متن کاملTargeted worm micelles.
Giant and stable worm micelles formed from poly(ethylene glycol) (PEG)-based diblock copolymer amphiphiles have the potential advantage compared to smaller assemblies for delivery of a large quantity of hydrophobic drugs or dyes per carrier. Here we show that worm micelles can be targeted to cells with internalization and delivery of nontoxic dyes as well as cytotoxic drugs. Constituent copolym...
متن کاملCurvature-driven molecular demixing in the budding and breakup of mixed component Worm-like Micelles.
Amphiphilic block copolymers of suitable proportions can self-assemble into surprisingly long and stable worm-like micelles, but the intrinsic polydispersity of polymers as well as polymer blending efforts and the increasing use of degradable chains all raise basic questions of curvature-composition coupling and morphological stability of these high curvature assemblies. Molecular simulations h...
متن کاملCo-assembly of Patchy Polymeric Micelles and Protein Molecules.
The development in the synthesis and self-assembly of patchy nanoparticles has resulted in the creation of complex hierarchical structures. Co-assembly of polymeric nanoparticles and protein molecules combines the advantages of polymeric materials and biomolecules, and will produce new functional materials. Co-assembly of positively charged patchy micelles and negatively charged bovine serum al...
متن کاملElectric field manipulation of charged copolymer worm micelles.
Manipulation of diblock copolymer worm micelles by external electric fields is visualized by fluorescence microscopy in dilute, aqueous solution. Hydrodynamic coupling of the poly(acrylic acid)-(1,4)-polybutadiene (PAA-PBD) worm motion to the electric field and the effective stiffening of the worms in an oscillating electric field are demonstrated. A brief discussion on using this technique to ...
