چکیده

We report the preparation of polyglycerol particles on different length scales by extending the size of hyperbranched polyglycerols (3 nm) to nanogels (32 nm) and microgels (140 and 220 μm). We use miniemulsion templating for the preparation of nanogels and microfluidic templating for the preparation of microgels, which we obtain through a free-radical polymerization of hyperbranched polyglycerol decaacrylate and polyethylene glycol-diacrylate. The use of mild polymerization conditions allows yeast cells to be encapsulated into the resultant microgels with cell viabilities of approximately 30%.

Hyperbranched Polyglycerols with Bisphenol a Core as Glycerol-derived Components of Polyurethane Wood Adhesives

Two hyperbranched polyglycerols (HBPGs) and one oligoglycerol containing bisphenol A in the core of the molecule were synthesized from glycerol carbonate and applied as polyols in 2-component polyurethane adhesive systems. It was shown that mechanical performance of the joints made in solid wood depended on the hydroxyl functionality of the polyglycerol as well as on the type of the isocyanate ...

Adsorption mechanism and valency of catechol-functionalized hyperbranched polyglycerols

Nature often serves as a model system for developing new adhesives. In aqueous environments, mussel-inspired adhesives are promising candidates. Understanding the mechanism of the extraordinarily strong adhesive bonds of the catechol group will likely aid in the development of adhesives. With this aim, we study the adhesion of catechol-based adhesives to metal oxides on the molecular level usin...

Micrometer-Scale Patterning of Multiple Dyes on Hyperbranched Polymer Thin Films Using Photoacid-Based Lithography

Micrometer-scale patterns of eosin and dansyl dyes on hyperbranched poly(acrylic acid) (PAA) organic thin films have been prepared using a combination of photoacid-based lithography and covalent grafting of dye molecules. Reflection infrared spectroscopy, optical microscopy, and fluorescence microscopy indicate that the dyes were attached within the intended regions. Patterned dye features havi...

Modular synthesis of multivalent glycoarchitectures and their unique selectin binding behavior.

Hyperbranched polyglycerols (HPGs) are ideal scaffolds for the multivalent presentation of saccharides, due to their biocompatible, carbohydrate-like properties; here, we report the conjugation of galactosesugar moieties to HPG, and the multivalent effect of these constructs on selectin binding.
