TOF-SIMS analysis of cell membrane changes in functional impaired human macrophages upon nanosilver treatment

Autor: Tentschert, J., Draude, F., Jungnickel, H., Haase, A., Mantion, Alexandre, Galla, S., Thuenemann, Andreas F., Taubert, Andreas (Prof. Dr.), Luch, A., Arlinghaus, H. F.

Silver nanoparticles (SNP) are among the most commercialized nanoparticles. Here, we show that peptide-coated SNP cause functional impairment of human macrophages. A dose-dependent inhibition of phagocytosis is observed after nanoparticle treatment,

ToF-SIMS and Laser-SNMS analysis of macrophages after exposure to silver nanoparticles

Autor: Draude, F., Galla, S., Pelster, Axel, Tentschert, J., Jungnickel, H., Haase, Alfred, Mantion, Alexandre, Thuenemann, Andreas F., Taubert, Andreas (Prof. Dr.), Luch, A., Arlinghaus, H. F.

Silver nanoparticles (SNPs) are among the most commercialized nanoparticles because of their antibacterial effects. Besides being employed, e. g. as a coatingmaterial for sterile surfaces in household articles and appliances, the particles are also u

Silicification of peptide-coated silver nanoparticles-A biomimetic soft chemistry approach toward chiral hybrid core-shell materials

Autor: Graf, Philipp, Mantion, Alexandre, Haase, Andrea, Thuenemann, Andreas F., Masic, Admir, Meier, Wolfgang P., Luch, Andreas, Taubert, Andreas (Prof. Dr.)

Silica and silver nanoparticles are relevant materials for new applications in optics, medicine, and analytical chemistry. We have previously reported the synthesis of pH responsive, peptide-templated, chiral silver nanoparticles. The current report

Solid-supported amphiphilic triblock copolymer membranes grafted from gold surface

Autor: Rakhmatullina, Ekaterina, Mantion, Alexandre, Buergi, Thomas, Malinova, Violeta, Meier, Wolfgang

Publikováno v: Journal of Polymer Science. A, Polymer Chemistry, Vol. 47, No 1 (2009) pp. 1-13

Surface-initiated ATRP was applied for the step-by-step growth of the biomimetic amphiphilic block copolymer membrane on a gold support. Different thicknesses of membranes were achieved through the variation of the polymerization conditions. The OH-g

Peptide-coated silver nanoparticles : synthesis, surface chemistry, and pH-triggered, reversible assembly into particle assemblies

Autor: Graf, Philipp, Mantion, Alexandre, Foelske, Annette, Shkilnyy, Andriy, MaÜic, Admir, Thuenemann, Andreas F., Taubert, Andreas (Prof. Dr.)

Simple tripeptides are scaffolds for the synthesis and further assembly of peptide/silver nanoparticle composites. Herein, we further explore peptide-con trolled silver nanoparticle assembly processes. Silver nanoparticles with a pH-responsive peptid

Silver nanoparticle engineering via oligovaline organogels

Autor: Taubert, Andreas, Fromm, Katharina, Foelske, Annette, Painsi, Monika, Guex, A.G., Mirolo, Laurent, Mantion, Alexandre

L-Valine-based oligopeptides with the chemical structure Z–(L-Val)₃–OMe and Z–(L-Val)₂–L-Cys(S-Bzl)–OMe form stable organogels in butanol. Both peptides are efficient gelators, but Z–(L-Val)₂–L-Cys(S-Bzl)–OMe crystallizes more r

'Unus pro omnibus, omnes pro uno' : using single amino acids as templates for biomineralization, and small self assembling peptides for the preparation of metal oxides, organization of metal nanoparticles and creation of new porous materials

Autor: Mantion, Alexandre

Introduction General concepts involved in the scope of this PhD Thesis are briefly presented. Part I: Bioinspired iron oxide mineralization Using single amino acids may be thought an over-simplification of larger proteins or peptides. However, their
