Triblock copolymers for cytoplasmic delivery of gene-based drugs
The invention features a triblock copolymer including a hydrophilic block a hydrophobic block and a positively charged block capable of reversibly complexing a negatively charged molecule, e.g., a nucleic acid, wherein the hydrophobic block is disposed bet ...
2007Functional polymer brushes via surface-initiated controlled radical polymerizations
The term polymer brush refers to a well defined arrangement of polymer chains, which are tethered with one end to an interface and usually the surface of a solid substrate. Due to steric repulsion the polymer chains furthermore adopt a defined, stretched c ...
EPFL2007Amphiphilic multi-arm star-block copolymers for encapsulation of fragrance molecules
Harm-Anton Klok, John Christopher Plummer, Céline Ternat
Novel amphiphilic multi-arm star-block copolymers with a hyperbranched core, a hydrophobic inner shell, and a hydrophilic outer shell have been prepared from a commercial hyperbranched polyester macroinitiator by ring-opening polymerization of -caprolacton ...
2007Design of amphiphilic nanocapsules based on hyperbranched star-block copolymers for the encapsulation and the controlled release of olfactory compounds
Effective encapsulation of small, volatile, weakly water-soluble molecules such as flavors and fragrances is necessary to protect them from degradation, to increase their lifetime, and to improve their water dispersion and fixation depending on the substra ...
EPFL2007Synthesis, structural characterization and applications of hyperbranched polymers based on L-lysine
L-lysine is an essential a-amino acid and a necessary building block for all proteins in the body. As an essential amino acid, L-lysine is not synthesized by humans or animals. Industrially produced L-lysine has therefore a big market as food additive, e.g ...
EPFL2007Hydrogen bonding and coordination in normal and supercritical water from x-ray inelastic scattering
A direct measure of hydrogen bonding in water under conditions ranging from the normal state to the supercritical regime is derived from first-principles calculations for the Compton scattering of inelastically scattered x rays. First, we show that a measu ...
2007Molecular Imprinting with Ruthenium Porphyrin Catalysts
A ruthenium meso-tetra[4-(vinylbenzoxy)benzyl]porphyrin catalyst with four polymerizable side chains was synthesized in three steps from commercially available starting materials. The polymerizable side chains allowed the incorporation of this complex in h ...
2006Magnetic and electrostatic effects on the polymerization of water-soluble monomers
Free radical polymerization is the most frequently used technique to produce synthetic polymers. They represent more than 25% of the total volume of materials made by the mankind. 3% thereof correspond to water soluble polymers with annual growth rates est ...
EPFL2006Ferrocene-Containing Optically Active Liquid-Crystalline Side-Chain Polysiloxanes with Planar Chirality
Optically active liquid-crystalline side-chain polysiloxanes have been prepared by grafting planar chiral ferrocene-based vinyl monomers onto commercially available polyhydrosiloxane. Two ferrocene monomers have been synthesized: a linear-type monomer, whi ...
2006Solid-state structure, organization and properties of peptide-synthetic hybrid block copolymers
Peptide-synthetic hybrid block copolymers are most easily prepared via ring-opening polymerization of ?-amino acid N-carboxyanhydrides using appropriately end-functionalized synthetic polymers as the macroinitiator. This class of peptide-synthetic hybrid b ...
