Researchers at University of Texas Southwestern Medical Center, Dallas, USA, have determined that light reflectance spectroscopy can differentiate between malignant and benign prostate tissue with 85% accuracy.
New method allows hyperpolarised xenon gas, to be dissolved into minute samples of substances without disrupting their molecular order during NMR spectroscopy.
Terahertz radiation is of growing interest due to its potential for new spectroscopy and imaging applications as well as wireless communication networks with extremely high bandwidth. However, there are few off-the-shelf components available for manipulating terahertz waves.
Fluorescence spectroscopy has been used to study the ancient pigment, Egyptian blue.
Entries for the IRDG Chalmers and Dent Student Travel Award for a PhD to present their research at the SciX meeting.
The protein α-synuclein plays an important role in Parkinson’s and other neurodegenerative diseases. Although a considerable amount is known about the structure of the protein within the Parkinson’s-typical amyloid deposits, nothing was known about its original state in the healthy cell up to now. High-resolution nuclear magnetic resonance and electron paramagnetic resonance spectroscopy have helped to visualise the protein in healthy cells.
We are all probably aware of the detection of metabolites in wastewater to indicate the levels of illegal drug usage in a locality, but researchers at the University of Valencia have extended this to monitor alcohol consumption in near real time.
Fake or low-quality medicines and food supplements are a continuing global problem in developing nations, and indeed the developed world is not immune. A low-cost, portable prototype using nuclear quadrupole resonance spectroscopy can detect tainted medicines and food supplements.
Terahertz imaging technology has the potential to help conservationists and academics better understand the history behind cultural artefacts.
A chip-based device can generate a laser signal with frequencies spaced in a comb-like fashion. In general, light and water waves alike stretch out and dissipate as they move further and further away from their source. However, there is a type of wave that maintains its shape as it propagates: solitons.
A new test for detecting biomarkers for cancer and diabetes based on two-dimensional mass spectrometry is more than 1000× more detailed and 100% faster than existing methods, new research by the University of Warwick, UK, suggests.
- Special issue shows how mass spectrometry is transforming clinical testing
- Single molecule detection in gas-, solid- or liquid phases possible with slippery SERS
- Frequency-agile laser frequency combs enable real-time NIR spectroscopy
- New mass spectrometry test for cancer and diabetes biomarkers 1000x more detailed
