Journal Highlight: Estimation of spectra sample size for characterizing single cells using micro-Raman spectroscopy

Date: May 2, 2016

Author: spectroscopyNOW

A study of the effects of sample size on the ability to generate single-cell Raman spectra that accurately describe the total molecular content of the cell demonstrates the importance of adequate spectral sampling.

Journal Highlight: Ultrafast Multidimensional Laplace NMR Using a Single-Sided Magnet

Date: May 2, 2016

Author: spectroscopyNOW

Ultrafast single- and multidimensional Laplace NMR experiments, based on spatial encoding, are shown to be viable with low-field, single-sided magnets with an inhomogeneous magnetic field.

Journal Highlight: Preconcentration of bismuth(III) by ultrasound assisted emulsification solidified floating organic drop microextraction and analysis by atomic absorption spectrometry

Date: May 2, 2016

Author: spectroscopyNOW

Ultrasound-assisted emulsification solidified floating organic drop microextraction was used for preconcentration of trace amounts of bismuth in environmental water prior to its determination by flame atomic absorption spectrometry.

Archaeological bones: Collagen peptides reveal species

Date: May 1, 2016

Author: Steve Down

A new mass spectrometric method for identifying small mammal species from the collagen in archaeological bones will allow the rapid analysis of large numbers of samples to help establish the correct history of a site.

Dioxin exposure: Human protein biomarkers of TCDD

Date: May 1, 2016

Author: Steve Down

Scientists in the Republic of Korea have identified a number of proteins in human hepatocyte cells that are affected by low doses of 2,3,7,8-tetrachloro-p-dioxin and could act as toxicological biomarkers. Some of them were subsequently found in the blood of exposed incineration workers.

The hidden chemicals in so-called ‘herbal’ diet pills

Date: May 1, 2016

Author: Ryan De Vooght-Johnson

Following numerous diet pill safety scandals, herbal medicines are becoming increasingly popular in the fight against the flab. In a new study from Belgium, scientists used chemical fingerprinting to analyse supposedly herbal diet pills – the first time fingerprinting has been used to evaluate the safety of illegal slimming aids.

Lymph check: SPECT-MRI detects cervical metastases

Date: May 1, 2016

Author: David Bradley

Cervical cancer patients who do not have enlarged lymph nodes could benefit from imaging using SPECT-MRI imaging to determine whether their sentinel lymph nodes (SLNs) have become metastatic, according to a new study published in The Journal of Nuclear Medicine.

Ulcerative colitis: Infrared diagnostics

Date: May 1, 2016

Author: David Bradley

Infrared technology could be key to minimally invasive screening for an often debilitating and worrying condition, ulcerative colitis. Moreover, the technology could offer a rapid, simpler and cost-effective diagnostic method that precludes the need for surgical biopsies and intrusive testing of the body, according to researchers at Georgia State University.

Integrated solar energy: EDS lights up

Date: May 1, 2016

Author: David Bradley

Energy-dispersive X-ray spectroscopy (EDS) has been used by researchers in China to study semiconducting sulfides for full-spectrum solar energy conversion with the benefit of efficient charge separation.
