Nanomembranes with pore molecules for efficient filtration

Method offers the promise of many possible applications across the chemical and pharmaceutical industries

05-Sep-2022 - A team from Bielefeld University, Queen Mary University of London, Imperial College London (both United Kingdom) and Northwestern University in Evanston (USA) have produced a new breed of polymer nanomembranes with aligned supramolecular macrocycle molecules. These new nanomembranes demonstrate ...

Low-cost production of RNA-based vaccines and active substances

Cost-effective and flexible production systems for RNA-based active ingredients

30-Jun-2021 - Over the next three years, scientists at the Centre for Biotechnology (CeBiTec) at Bielefeld University will be working on cost-effective and flexible production systems for RNA-based active substances. These substances are required for vaccines and pesticides, for example. The German Federal ...

New method leads ten times faster to corona test results

Method not only saves time, but also effort

10-Jul-2020 - Currently, it takes more than two hours to perform and evaluate a test for SARS-CoV-2 - and so a laboratory can only test a very limited number of people per day. Cell biologists at the University of Bielefeld have now developed a method in a study with several cooperation partners that delivers ...

A Hormone-Plant Style

Researchers develop biotechnological production process

03-Jun-2020 - Plants produce the hormone jasmonic acid as a defence response when challenged. This is how they ensure that their predators no longer like the taste of their leaves. Biologists want to find out whether biological precursors and other variants of jasmonic acid lead to similar or different ...

Motion pictures from living cells

Research team improves superresolution microscopy

24-Sep-2019 - In order to observe cells at work, researchers have to bypass a physical law. One of the fastest techniques to overcome the resolution limit of classical light microscopy is high-resolution structured illumination microscopy. It makes visible details that are about a hundred nanometres in size. ...

Pharmaceutical Production with Reduced Waste

Platform technology for producing cephalosporin antibiotics

18-Jun-2019 - Antibiotics save countless human lives – modern medicine without them is unimaginable. The largest proportion by volume of industrially produced antibiotics today are cephalosporins, structural variants of the first antibiotic, penicillin. Unfortunately, their production generates a considerable ...

Chip-based nanoscopy: Microscopy in HD quality

27-Apr-2017 - This information can be used to produce images with a resolution of about 20 to 30 nanometres, and thereby ten times that of conventional light microscopy. Until now, this method has required the use of expensive special instruments. Bielefeld University and the University of Tromsø have filed a ...

Starship Enterprise concept: Optical tractor beam traps bacteria

High resolution cell imaging

15-Dec-2016 - Up to now, if scientists wanted to study blood cells, algae, or bacteria under the microscope, they had to mount these cells on a substrate such as a glass slide. Physicists at Bielefeld and Frankfurt Universities have developed a method that traps biological cells with a laser beam enabling them ...

Trapping and watching motile cells

A new approach enables rapid characterization of living suspension cells in 4 dimensions

01-Apr-2015 - Optical imaging of highly motile cells or cells in suspension, such as bacterial systems, yeast cells, and immune cells, is a challenging task, in many cases it is just not possible. The human immunodeficiency virus (HIV), for example, can spread very efficiently from an infected T cell to an ...

Neu entschlüsseltes Bakteriengenom soll pharmazeutisch wirksame Substanzen liefern

Bundesforschungsministerium fördert GEnomikPlus-Netzwerk an der Saar-Uni mit 350.000 Euro

23-Aug-2006 - Im Institut für Pharmazeutische Biotechnologie von Professor Dr. Rolf Müller an der Universität des Saarlandes wurde kürzlich in Kooperation mit der Universität Bielefeld und dem Helmholtz-Zentrum für Infektionsforschung (HZI) in Braunschweig die komplette Genomsequenz des Bakteriums Sorangium ...
