Answers to Endangered Animals Lies in their Scat

LC-MS for Animal Identification

LC-MS for Animal Identification

Studying rare or endangered species of wild animals is no easy task. Analysis of animal tracks and fecal matter left behind can provide some clues for species identification, as well as insight into animal behavior and habitation. However, these identification signs are elusive, and often confounded by variations in environmental conditions, as well as animal health and diet. While methods of molecular analysis such as DNA sequence analysis of animal scat samples can provide more informative answers, DNA contamination from other mammals can make accurate identification difficult. To circumvent some of these limitations, Udaya Nasini, Ali Shaikh and colleagues from the University of Arkansas in Little Rock, USA, have demonstrated the use of liquid chromatography-mass spectrometry (LC-MS) to determine the composition of bile acids in scat samples. Analysis using LC-MS provides a metabolic pattern that is characteristic of a distinct species, and in turn enables effective identification.

Learning How to Use PARAFAC for Fluorescence Spectroscopy

PARAllel FACtor analysis (PARAFAC) has been a tremendously instrumental tool for interpreting a wide-range of information including spectral, NMR, GS-MS, (HP)LC-DAD, EEG, geospatial, radar, sensory, metabolomic and image data. In effect, application of PARAFAC has resulted in advancements for diverse research areas including medical, pharmaceutical, food, environmental, social and information science. Notably, PARAFAC applications pertaining to analysis of fluorescence excitation emission matrices have been particularly popular. However, users are often confronted with many practical and analytical challenges when using PARAFAC for real-life applications.

To help simplify this procedure, Kathleen R. Murphy from Australia, along with Colin A. Stedmon and other colleagues from Denmark, provide an informative tutorial of the practical application of PARAFAC for fluorescence data analysis. This review provides deeper insight into preparing, modelling and interpreting fluorescence datasets particularly for environmental samples, and demonstrates a new software tool to facilitate PARAFAC analysis.

A Global Vision on Nanoparticles

Lopez-Serrano et al., Anal. Methods, 2013

Nanoparticles are broadly defined as particles with at least one external dimension between 1-100 nm. Due to their small scale, the physico-chemical properties of nanoparticles often differ from those of their corresponding bulk material. These extraordinary properties have sparked a great deal of interest in nanoparticles for a wide range of applications, massively increasing their use in consumer products and ultimately their release into the environment. The chemical composition, structure, size, and shape of nanoparticles can significantly impact on environment and health. Analysis and characterisation of nanoparticles is therefore extremely important to understand their potential toxicity.
In their review, Carmen Cámara and colleagues at the University Complutense of Madrid, Spain, highlight the challenges faced by scientists and policy makers in assessing the safety and impact of nanoparticles due to the lack of standardised procedures. According to the authors, the properties that make these novel materials so appealing to industry may also be responsible for enhanced human and environmental toxicity.

The review covers a wide range of topics within nanotoxicology and it is of great interest to anyone looking for a detailed overview of the field. The section on nanoparticle analysis thoroughly describes the uses and pitfalls for the various analytical techniques available and discusses important topics such as nanoparticle extraction/enrichment and size fractionation.
