Improved analysis of perfluorinated compounds
Susan Wolf and William Reagen optimised a new analytical method to study perfluorinated compounds in water. The pre-sampling isotope dilution direct injection liquid chromatography tandem mass spectrometry presented here is the first example of isotope dilution with a 28 days sample holding time applicable to drinking and environmental water.

Novel silver nanocluster to detect cholesterol
Cholesterol levels are important parameters often related to a wide range of diseases. Deficiency of cholesterol for instance can result in hyperthyroidism and malabsorption, whereas excess of cholesterol may cause nephrosis and diabetes mellitus. Ruqin Yu and others from the Hunan University in China developed a new and cost-effective silver nanocluster fluorescent sensor for efficient detection of cholesterol.
