Hyperbranched polymer vesicles: from self-assembly, characterization, mechanisms, and properties to applications
Vesicles, including lipid vesicles, surfactant vesicles, as well as polymer vesicles, have been extensively investigated over the past fifty years. Among them, polymer vesicles have attracted more and more attention because of their low permeability, superior stability and toughness, in addition to the numerous possibilities for tailoring physical, chemical and biological properties. Polyme...

Improvement of gene delivery of PDMAEMA by incorporating a hyperbranched polymer core
A novel strategy to improve the transfection efficiency as well as lower the cytotoxicity for PDMAEMA polycationic vectors has been developed. The cytotoxicity decreases and the transfection efficiency increases significantly through the incorporation of a hydrophobic hyperbranched PEHO core into PDMAEMA. The effectiveness of the hyperbranched architecture for the gene transfection was further p...

Supramolecular Self-Assembly of Giant Polymer Vesicles With Controlled Size
An ill-defined hyperbranched multiarm copolymer (see picture) with a high hydrophilic fraction (>60?%) self-assembles in water to form giant polymer vesicles (branched polymersomes). The size of the branched polymersomes can be easily controlled by adjusting the hydrophilic fraction of the copolymer, with the average diameter of the larger branched polymersomes exceeding 100 μm.

Preparation of Magnetic Molecularly Imprinted Polymer Beads and Their Recognition for Baicalein
Magnetite-β-cyclodextrin@poly(ethyleneglycol dimethacrylate-co-methacrylic acid)
core-shell microspheres imprinted with baicalein (Fe3O4-β-CD@MIPs) were
synthesized by ultrasonic assisted precipitation polymerization (UAPP) using
methacrylic acid (MAA) as functional monomer and EGDMA as crosslinker in
presence of Fe3O4-β-CD nanoparticles as template and baicalein (BAI) as imprinting
molecule. T...

Polymer microspheres as a scaffold for nitric oxide release in PBS buffer and bovine serum
This paper reports the design, preparation and
characterization of functional polymer microsphere as a reservoir for nitric
oxide (NO)-release. Silica/polymer core-shell microspheres and the
corresponding hollow functional polymer microspheres with secondary amino
groups were converted to N-diazeniumdiolate
as scaffolds for nitrogen oxide (NO) release. The silica/polymer core-shell
microspher...

Magnetic Superhydrophobic Polymer Nanosphere Cage as a Framework for Miceller Catalysis in Biphasic Media
This study demonstrated the use of a magnetic superhydrophobic polymer nanosphere cage derived from a Pickering emulsion as a framework for miceller catalysis in biphasic media. We designed this system through the covalent stabilisation of active site (2,2,6,6-tetramethylpiperidine 1-oxyl)-grafted amphiphiles onto the magnetic hydrophobic core to form a micelle-like architectur...

Heavy Metal Ions Removal by Nano-Sized Spherical Polymer Brushes
Nano-sized spherical polymer brushes (SPBs) consisting of both a polystyrene (PS) core and a brush shell of poly (acrylic acid ) (PAA), poly(N-acrylcysteamine) (PSH), or poly(N-acrylcysteamine-co-acrylic acid) (P(SH-co-AA)), were prepared by photo-emulsion polymerization. The core-shell structure was observed by dynamic light scattering and transmission electron microscopy. Due to the strengthen...
