New light source: A million times brighter than the sun

PhD thesis investigated application of a special white-light laser for semiconductor industry and microbiology

14-Feb-2022 - A new high-performance white-light laser is expected to speed up quality control in the semiconductor industry and provide closer monitoring of toxicity tests in microbiology. In one step, this laser enables the two-sided characterization of surfaces and can be integrated into production chains. ...

Nanostructures with living cells

06-Feb-2013 - Using Laser Technology, Aleksandr Ovsianikov from the Vienna University of Technology wants to create microstructures with embedded living cells. This project will be funded by an ERC Starting Grant. The behavior of cells strongly depends on their environment. If they are to be researched an ...

Fewer animal experiments thanks to nanosensors

12-Jan-2012 - Countless mice, rats and rabbits die every year in the name of science – and the situation is getting worse. While German laboratories used some 2.41 million animals for scientific research in 2005, by 2009 this number had grown to 2.79 million. One third were destined for fundamental biology ...

Portable and precise gas sensor could monitor pollution and detect disease

22-Sep-2009 - In the air, it is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function. Nitric oxide, a gas well known to scientists for its myriad functions, has proven challenging to measure accurately outside the laboratory. A team of Princeton and ...

Fitting pieces for biosensors

15-Apr-2009 - Research and industry are increasingly exploiting the potential of aptamers. As well as their application in research, medical diagnosis and treatment, aptamers are also interesting as a basis for biosensors for use in environmental analysis because their characteristics enable them to identify ...

The Nobel Prize in Physiology or Medicine 2007

09-Oct-2007 - The Nobel Assembly at Karolinska Institutet has decided to award The Nobel Prize in Physiology or Medicine for 2007 jointly to Mario R. Capecchi, Martin J. Evans and Oliver Smithies for their discoveries of "principles for introducing specific gene modifications in mice by the use of embryonic ...

New Methods for Screening Nanoparticles

23-Aug-2006 - Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. This has led to the visualization of how human cells interact with some ...

Bruker Daltonics and German Collection of Microorganisms and Cell Cultures Identify Microorganisms by Mass Spectrometry

23-Feb-2006 - Bruker Daltonik GmbH and the German Collection of Microorganisms and Cell Cultures (DSMZ) announced a collaboration for the identification and classification of microorganisms from peptide and protein profiles measured by MALDI-TOF mass spectrometry. The DSMZ uses Bruker Daltonik´s novel CLINPROT ...

Tiny Tubes for Biotransport

Researchers clarify cellular uptake mechanisms for carbon nanotubes

08-Dec-2005 - They look like the tiniest of needles and have the potential to channel pharmaceutical agents into targeted living cells: carbon nanotubes are long, thin, nanoscale tubes made of one (or more) layers of carbon atoms in a graphite-like arrangement. Drugs can be hooked on to their exteriors and can ...
