Fuel bioethanol production from whey permeate

The objective of this thesis was to evaluate the feasibility for the production of fuel bioethanol from whey permeate. The identification of the limiting factors of the process revealed that the stabilization of the substrate was critical to the use of whe ...

Use of self-actuating and self-sensing cantilevers for imaging biological samples in fluid

Georg Fantner

In this paper, we present a detailed investigation into the suitability of atomic force microscopy (AFM) cantilevers with integrated deflection sensor and micro-actuator for imaging of soft biological samples in fluid. The Si cantilevers are actuated using ...

Integration of plasmonic trapping in a microfluidic environment

Olivier Martin, Sebastian Maerkl, Lina Huang

Near field generated by plasmonic structures has recently been proposed to trap small objects. We report the first integration of plasmonic trapping with microfluidics for lab-on-a-chip applications. A three-layer plasmo-microfluidic chip is used to demons ...

Data Reconciliation of Concentration Estimates from Mid-Infrared and Dielectric Spectral Measurements for Improved On-Line Monitoring of Bioprocesses

Dominique Bonvin, Urs von Stockar, Ian William Marison, Michael Amrhein, Michal Dabros

Real-time data reconciliation of concentration estimates of process analytes and biomass in microbial fermentations is investigated. A Fourier-transform mid-infrared spectrometer predicting the concentrations of process metabolites is used in parallel with ...

Cytokinesis: Closure resets your SIN

Viesturs Simanis, Andrea Krapp, Evelyn Lattmann

A new study of fission yeast cell division has revealed a coupling between cytoplasmic partitioning and the turning-off of cytokinesis signalling that may be mediated by asymmetric protein distribution. ...

Controlled entrapment of cells in hydrogels on chip and cell sorting by dielectrophoresis using liquid electrodes

Thomas Michael Braschler

Alginate gel formation on-chip is presented in the first part of this thesis. The technique allows immobilization, and release, of biological cells on-chip. Furthermore, via layer by layer deposition, a locally heterogeneous environment can be generated at ...

Dielectrophoresis-based continuous-flow particle microreactor

Raphaël Tornay

This thesis mainly deals with the integration of a microfluidic system for the extraction of micrometric and submicrometric particles from a solution. Traditional methods take from several minutes to hours to separate particles from a solution. Microfluidi ...

Dynamic modeling of the TOR signaling pathway in yeast

Irina Krier

This Master thesis presents a complete cycle in the use of models for the study of a complex pathway like the TOR pathway. Previous models were reproduced for the phosphatase part of the pathway, and the assumptions used and the results they provided were ...

Functional differentiation of tbf1 orthologues in fission and budding yeasts

Viesturs Simanis, Elena Cano

In Saccharomyces cerevisiae, TBF1, an essential gene, influences telomere function but also has other roles in the global regulation of transcription. We have identified a new member of the tbf1 gene family in the mammalian pathogen Pneumocystis carinii. W ...

Related mechanisms for end processing at telomeres and DNA double-strand breaks

Joachim Lingner, Nahid Iglesias

In a recent issue of Molecular Cell, Bonetti et al. (2009) identify in the yeast Saccharomyces cerevisiae that the molecular activities that generate 3' overhangs at telomeric DNA ends are the same as those that resect DNA at double-strand breaks. ...
