Protein-polymer conjugates are widely used in biotechnology and medicine, and non-toxic polymers for bioconjugation would be advantageous for these applications. Herein, we reported the toxicity of polymers synthesized by two commonly employed controlled r ...
We report on a novel microsynthesis method for easy controlling the size of silica micro- and nanoparticles. Colloids are synthesized in a microfluidic chamber by layer-wise adsorption of silica to precipitated nuclei. We prepare samples of spherical parti ...

Insight into the conformations and aggregation of alginic acid was gained by measuring its diffusion coefficient at very dilute concentrations using fluorescence correlation spectroscopy. Both the pH and ionic strength (I) had an important influence on the ...
Nanoporous films of cryst. anatase with intended application in dye-sensitized photovoltaic cells were studied by NMR cryoporometry, NMR diffusiometry, electron microscopy, and x-ray diffraction. The nanoparticles from which the films were subsequently sin ...
The coupling of the flow field flow fractionation to differential refractive index (DRI) and multi-angle laser light scattering detectors is a powerful tool for characterizing charged polysaccharides such as alginate. However, the correct interpretation of ...
Mixed ionic–electronic conducting La0:5Sr0:5 Fe1 xBxO3 δ (B: Al, Cr, Zr, Ga, Ti, Sn, Ta, V, Mg, and In with x=0, 0.1, 0.2) perovskite materials were produced via solid-state synthesis. In order to study the effect of Bsite substitution on the expansion beh ...
This thesis reports on the development of technologies and methods for a microfiuidic device for continuous pressure-driven flow-injection analysis. Chip based, pressure-driven liquid chromatographic (LC) systems are often avoided due to the difficulties e ...
The growing demand for high levels of recombinant proteins of medical and pharmaceutical interest stimulates the development of cell bioprocess technology. Spin-filter technology is employed in order to reach high levels of such compounds. The aim of this ...
Colloidal Ag nanoparticles were formed by X-ray irradiation in the presence of a polymer. This new synthesis method is simple, rapid and leads to a high production yield. Compared to the citrate-reduced Ag colloidal, polymer-protected Ag nanoparticles are ...
Expts. of Me methacrylate dispersion polymn. are carried out in a reaction calorimeter using PDMS-mMA (methacrylate-terminated polydimethylsiloxane) as surfactant. Different stabilizer concns. from 0 to 10 wt% with respect to monomer have been considered i ...
