Sol-gel processes applied to micro- and nanotechnology

Jean-Baptiste Robert Orhan

In this thesis, we intend to develop the sol-gel technology (a chemical way to make glass) from the traditional "raw" materials side to a novel technology allowing realization of innovative products in the field of micro- and nanotechnology. We first prese ...

Characterization of the mechanism of action of spin-filters for animal cell perfusion cultures

Florentina Vallez

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 ...

Formation of Microcapsules from Polyelectrolyte and Covalent Interactions

Urs von Stockar, Ian William Marison, Véronique Breguet

A new approach combining electrostatic and covalent bonds was established for the formation of resistant capsules with long-term stability under physiol. conditions. Three kinds of interactions were generated in the same membrane: (1) electrostatic bonds b ...

Polyimide microfluidic devices with integrated nanoporous filtration areas manufactured by micromachining and ion track technology

Philippe Renaud, Arnaud Bertsch, Stefan Metz

This paper reports on polyimide microfluidic devices fabricated by photolithography and a layer transfer lamination technology. The microchannels are sealed by laminating an uncured polyimide film on a partially cured layer and subsequent imidization. Sele ...

Flexible microchannels with integrated nanoporous membranes for filtration and separation of molecules and particles

Philippe Renaud, Arnaud Bertsch, Stefan Metz

This paper reports on the technology development and characterization of polyimide-based, microfluidic channels with integrated nanoporous membranes. A layer transfer and lamination technique is used to fabricate flexible microchannels from spin-on polyimi ...
