Detection and identification of vitamin D metabolites in plant sources
A vitamin is defined as an organic molecule essential for health. Indeed, vitamin D has been associated with bone health and with immune-related effects, however a vitamin D deficiency has been associated with chronic diseases and mortality .
Multi-elemental analysis of diatoms using single-cell-ICP-TOF-MS
In today’s laboratories, elemental analysis methods are used for more than just determining total metal content in various sample matrices. They have become an important tool for life science research in environmental science, medicine and biology.
A comparison of different analysis techniques for determination and species analysis of mercury
Mercury is undisputedly one of the most toxic elements. In 2013, the Minamata Convention on Mer-cury to restrict the production and emission of this heavy metal was adopted in Geneva. It regulates the production, use and storage of mercury. For example, new mines may no longer be built and ...
Improving the efficiency of organic light emitting diodes with aromatic carbonyls
Organic light emitting diodes (OLEDs) are presently conquering the market for displays of smartphones and TVs. They also have a great potential in lighting applications. Current devices for the blue part of the visible spectrum lag behind their green and red counterparts in terms of efficiency ...
A novel microspectroscopic method allows sugar mapping across the plant tissue
Quantitative mapping of metabolite distribution has widespread applications in medicine and biology, but has remained a key analytical challenge. A novel method for sugar imag-ing in plants based on the principles of infrared spectroscopy, which was developed at the IPK-Gatersleben, allows the ...
An emerging technology to comprehensively describe entire lipid profiles
Progress in research is – to a large extent – driven by technological and analytical advance-ments. This is particularly true for the field of lipid research in the biomedical field, which was hampered for decades by the limited availability of analytical tools to address the enormous complexity ...
Using mass spectrometry to detect the presence of small polymer molecules
For several decades, food packaging has made handling food easier and helped to maintain its quality. Plastic packaging possesses the advantage that it is light and flexible, with a vast variety of polymer modifications allowing a wide range of usages.
Process analytics in biotechnology
As far back in time as several thousand years ago our ancestors were using biotechnical processes to make beer, wine and bread. These days, biotechnological processes are not merely used to produce food – they enable a wide variety of applications, from wastewater treatment to manufacturing ...
From protein mechanisms to tissue analysis
Spectroscopic methods are now granting us deep insights into biological systems at previously unattainable spatial and temporal resolutions. Complementing the already well-established fluorescence spectroscopy, the major potential of label-free vibrational spectroscopy has become clear in recent ...
Label-free and non-invasive Raman-Trapping microscopy
Analysis of single cells is never easy – and it gets even more difficult when cells are not fixed at a surface but freely moving. In this case, Raman-Trapping-Microscopy arrests motile samples during spectral analysis. These most powerful devices enable novel insights into characteristics and ...
q&more – the networking platform for quality excellence in lab and process
