Preparation of ion group functionalized diblock copolymers and examination of their thermogelling properties

Lee B.K., Kwon D.Y., Kwon J.S., Park J.H., Kwon D.Y., Kwon J.S., Kim J.H., Kim M.S., Oh S.H., Kim J.H., Kim M.S., Ajou University, KR

To investigate thermogelling behavior, in this study, methoxy polyethylene glycol-b-[poly(ε-caprolactone)-ran-poly(6-chloride-ε-caprolactone) (PCL-ran-PfCL)] (PCL-Cl) diblock copolymers were designed such that the PfCL content in the PCL segment was varied. The PCL-Cl diblock copolymers were derivatized by introducing [...]

Uptake Behavior of Glycoconjugated and Micellar-Encapsulated Quantum Dots on HeLa Cervical Cancer Cells

Merkl J.-P., Schmidtke C., Safi M., Muroski M., Alpers D., Tran H., Ostermann J., Kreuziger A.-M., Strouse G., Mattoussi H., Weller H., University of Hamburg, DE

Glyconanomaterials are of great interest for bio-imaging to understand biological processes, for instance metabolism, cell-cell or virus-cell interactions, gluconeogenesis, and cancer. Herein, we present a strategy for the biofunctionalization of fluorescent quantum dots (QDs) from [...]

Encapsulation of nanoparticles with multifunctional, cross-linkable diblock copolymers for biomedicine

Schmidtke C., Ostermann J., Tran H., Pöselt E., Kloust H., Niehaus J., Becker S., Kreuziger A., Werner K., Pietsch A., Weller H., University of Hamburg, DE

We would like to present a micellular encapsulation method for nanoparticles (quantum dots, iron oxides, gold) which is based on a ligand exchange procedure of native ligands with a prepolymer poly(isoprene)-diethylentriamine (PI-N3) and subsequent ligand [...]

From Games and Films to Molecular Simulation and Design

Olguin C., Zhao W., Autodesk, Inc., US

Propelled by the multi-billion dollar game and film industries, CG software has evolved dramatically in sophistication. Effects range from realistic explosions to the chaotic movement driven by wind and other fluids. This paper describes our [...]

Nanostructures fabrication via self-assembly of hybrid block copolymer/nanoparticles in thin film

Fahmi A., Gindy N., University of Nottingham, UK

Fabrication of Nanostructures via self-assembly process is an elegant concept for the production the next generation of miniaturised devices. However, many challenges need to be overcome in 2D and 3D nanofabrication before the routine utilisation [...]
