Infrared

Infrared spectroscopy and other techniques have been used by researchers in France to show how the biologically important gas molecule nitric oxide, NO, can be trapped within porous materials known as metal-organic frameworks (MOFs).

Nuclear Magnetic Resonance

An international team from Colombia and Germany has demonstrated how to use NMR spectroscopy to identify adulteration or contamination of coffee beans based on country of origin, a useful tool in the fight against food fraud in a high-value market.

Sample Preparation

Three antidepressants covering two different classes have been extracted from urine by a variation of dispersive liquid-liquid microextraction in which the sample is heated to assist derivatisation and extraction.

Proteomics

The biochemical responses of human muscles to extended periods of oxygen deprivation have been measured in participants of an expedition to Mount Everest using proteomics techniques.

Atomic

An in vitro study using atomic absorption spectroscopy has investigated the concentrations of calcium found in diverse green vegetables commonly used in Indian cuisine as well as allowing the researchers to comment on the availability for absorption from the diet of the calcium present in these edible plants.

Electrophoresis

Scientists in China and the US have used two-dimensional gel electrophoresis to investigate how the protein composition of the biocake that builds up on membranes used to treat wastewater changes over time.

Raman

The incorporation of heavy water into the biomolecules of bacteria has given an international research team the means to tease apart and identify the activities of different members of microbial communities using Raman microscopy.
