X-ray irradiation synthesis of PEG-coated Au-Pd nanoparticles

Giorgio Margaritondo

We demonstrate that the combination of x-ray irradiation and capping by polyethylene glycol (PEG) produces excellent flexibility in controlling the structure of Au-Pd nanoparticles while preserving their catalytic performance. We specifically adopted two d ...

MULTIFUNCTIONALIZED SPIONs FOR NUCLEAR TARGETING: CELL UPTAKE AND GENE EXPRESSION

Heinrich Hofmann, Alke Fink, Jatuporn Salaklang

Superparamagnetic iron oxide nanoparticles (SPIONs) are used in many biological applications, which necessitate intracellular targeting. Here, we investigate intracellular localization and gene expression in HeLa cells after treatment with functionalized S ...

Plasticization of polylactide foams for tissue engineering

Pierre-Etienne Bourban, John Christopher Plummer, Matthieu Cuénoud

Supercritical CO2 foaming of amorphous and semicrystalline polylactides plasticized by blending with 20 wt% polyethylene glycol has been investigated as a means of producing low-stiffness bioresorbable scaffolds for tissue engineering. For a given set of f ...

Arginine-Specific Modification of Proteins with Polyethylene Glycol

Harm-Anton Klok, Marc Gauthier

In this study, the residue-selective modification of proteins with polymers at arginine residues is reported. The difficulty in modifying arginine residues lies in the fact that they are less reactive than lysine residues. Consequently, typical chemo-selec ...

Plasticization of poly-L-lactide for tissue engineering

Pierre-Etienne Bourban, John Christopher Plummer, Matthieu Cuénoud

Plasticization of medical grade poly-L-lactide (PLLA) by addition of polyethylene glycol (PEG) with various molar masses has been evaluated as means of producing low stiffness matrices for bioresorbable scaffolds for soft-tissue engineering applications. A ...

Structuration of the low temperature co-fired ceramics (LTCC) using novel sacrificial graphite paste with PVA–propylene glycol–glycerol–water vehicle

Peter Ryser, Thomas Maeder, Caroline Jacq

A novel formulation for thick-film graphite sacrificial pastes is studied in this paper. It is composed of coarse graphite powder (grain size: 25 μm), dispersed in a vehicle consisting of polyvinyl alcohol (PVA) dissolved in a propylene glycol (PG)–glycero ...

(Y0.5Lu0.5)2O3:Eu3+ nanopowders: Combustion synthesis, structure and optical properties

Barbora Bártová

In this work we explored the possibility of obtaining nanocrystalline (Y0.5Lu0.5)2O3 powders, doped with europium and co-doped with praseodium, employing polymer complex solution synthesis. Polyethylene glycol, with average molecular weight 200, served bot ...

In vitro uptake of amphiphilic, hydrogel nanoparticles by J774A.1 cells

Jeffrey Alan Hubbell

We here report improved synthesis and in vitro interactions of amphiphilic hydrogel nanoparticles with the macrophage cell line J774A.1. Nanoparticles comprising dispersed hydrophobic nanodomains of poly(propylene glycol) within a continuous phase of hydro ...

Aggregation Behavior of Poly(ethylene glycol-bl-propylene sulfide) Di- and Triblock Copolymers in Aqueous Solution

Jeffrey Alan Hubbell, Conlin O'Neil, Jacques Dubochet

Block copolymers of poly(ethylene glycol)-bl-poly(propylene sulfide) (PEG-PPS) have recently emerged as a new macromolecular amphiphile capable of forming a wide range of morphologies when dispersed in water. To understand better the relationship between s ...

Surface modifications based on the cyanobacterial siderophore anachelin: from structure to functional biomaterials design

Karl Gademann, Jean-Yves Wach, Joanna Kobylinska, Tom Woods

This review describes the design, synthesis and evaluation of novel catechol based anchors for surface modification. The anachelin chromophore, the catecholate fragment of the siderophore anachelin from the cyanobacterium Anabaena cylindrica, allows for th ...
