Considerations of the Impacts of Cell-Specific Growth and Production Rate on Clone Selection-A Simulation Study

Florian Maria Wurm

For the manufacturing of complex biopharmaceuticals using bioreactors with cultivated mammalian cells, high product concentration is an important objective. The phenotype of the cells in a reactor plays an important role. Are clonal cell populations showin ...

Variability in arsenic methylation efficiency across aerobic and anaerobic microorganisms

Rizlan Bernier-Latmani, Arnaud Michel Gelb, Karin Lederballe Meibom, Karen Elda Viacava Romo

Microbially-mediated methylation of arsenic (As) plays an important role in the As biogeochemical cycle, particularly in rice paddy soils where methylated As, generated microbially, is translocated into rice grains. The presence of the arsenite (As(III)) m ...

Recent advances on sputtered films with Cu in ppm concentrations leading to an acceleration of the bacterial inactivation

Juan Kiwi, Sami Rtimi

This review focuses on the acceleration of the bactericidal and fungicidal effects by uniform, adhesive Cu-based nanocomposites on textile and thin polymer surfaces. The acceleration of the bacterial inactivation kinetics mediated by Cu, TiO2/Cu and ZrO2-T ...

Conjugating Biotin to Ruthenium(II) Arene Units via Phosphine Ligand Functionalization

Paul Joseph Dyson, Lucinda Kate Batchelor

Two-step functionalization of 4-diphenylphosphino benzoic acid with biotin afforded 2-(biotinyloxy)ethyl 4-(diphenylphosphanyl)benzoate (LP), that was subsequently used to synthesize the Ru(II) arene complexes [RuCl2(eta(6)-p-cymene)(LP)] (1), [Ru(C2O4)(et ...

Inkjet Printed Carbon Nanotube Electrodes for Measuring Pyocyaninand Uric Acid in a Wound Fluid Simulant and Culture Media

Hubert Girault, Andreas Stephan Lesch, Milica Jovic

Polyacrylamide-coated, carbon nanotube (PA/CNT)electrodes were prepared by an ink-jet printing process and used to measure pyocyanin and uric acid in a wound fluid simulant at 37 oC.These two moleculesare potential indicators of infection and therefore the ...

Synthetic 3D PEG-Anisogel Tailored with Fibronectin Fragments Induce Aligned Nerve Extension

Jeffrey Alan Hubbell, Matthias Lütolf, Delphine Lorraine Perle Blondel

An enzymatically cross-linked polyethylene glycol (PEG)-based hydrogel was engineered to promote and align nerve cells in a three-dimensional manner. To render the injectable, otherwise bioinert, PEG-based material supportive for cell growth, its mechanica ...

Optical microsystems for genetically engineered biosensors. Case study: Glucose monitoring

Bakul Jitendra Vinchhi

Diabetes is a global epidemic with millions of people dying from it every year. Progress in microelectronics and machine learning has led to a huge number of FDA approvals of devices for continuous monitoring and treatment of diabetes with one product usin ...

Chromate tolerance and removal of bacterial strains isolated from uncontaminated and chromium-polluted environments

Rizlan Bernier-Latmani, Zuzana Chromiková

Investigation of bacterial chromate tolerance has mostly focused on strains originating from polluted sites. In the present study, we isolated 33 chromate tolerant strains from diverse environments harbouring varying concentrations of chromium (Cr). All of ...

Computational Analysis of the Mutual Constraints between Single‐Cell Growth and Division Control Models

John McKinney, Neeraj Dhar, Gaëlle Madeleine Vuaridel, Ambroise Roger Vuaridel

Three models of division control are proposed to achieve cell size homeostasis: sizer, timer, and adder. However, few published studies of division control take into account the dynamics of single‐cell growth and most assume that single‐cell growth is expo ...

Development of an AFM-based nanomotion detection device for microbiological samples

Wojciech Chomicki

The main goals of this thesis pertain to the development of a device capable of detecting microorganism viability through monitoring the oscillations of a microscopic cantilever transducer, to improve the presently used device and to attempt to explain in ...
