Learning How to Use PARAFAC for Fluorescence Spectroscopy

18 Oct 2013

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.

From Database to Data Interpretation Using PARAFAC

A Global Vision on Nanoparticles

10 Oct 2013

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.

Analytical Methods Poster Prize: ICAVS-7 Conference, Kobe, Japan

01 Oct 2013

Analytical Methods Poster Prize: ICAVS-7 Conference, Kobe, Japan

We are please to announce that the Analytical Methods Poster Prize from the recent ICAVS-7 Conference held in August 2013 in Kobe, Japan has been awarded to Satoko Tanimoto.

Satoko has just finished working at Imperial College London as the AHRC/ESPRC Science and Heritage programme post-doctoral fellow from October 2010. She previously completed a 3 year Andrew W. Mellon Fellowship at the Department of Conservation and Scientific Research, British Museum, where she worked on a number of projects, using a range of analytical techniques, including the technical study of a large set of Italian Renaissance drawings that were included in the exhibition, Fra Angelico to Leonardo: Italian Renaissance Drawings, which took place from April to July 2010. This was a collaborative project with the Gabinetto Disegno e Stampe degli Uffizi.

Satoko has a first degree from the Kobe Pharmaceutical University (Chemistry and Pharmacy/Pharmacology) in Japan and a MSc in Environmental Sciences and Management from the University of San Francisco. She also spent a year as an intern at the Getty Conservation Institute, before completing her PhD research at the Institute of Archaeology, University College London. During her PhD, Satoko also spent several extended periods working in the Science Section at the Victoria and Albert Museum, as a tutor in the Conservation Department at the City and Guilds Art School and with the Courtauld Institute of Art on wall paintings in Ahhichatragarh Fort/Nagaur Fort, India.

Satoko is looking forward to pass on her experience and knowledge to MA students at the Conservation of Wall Paintings Department, the Courtauld Institute of Art in her next post.

Satoko’s recent AHRC/EPSRC Science and Heritage project at the Imperial College was to explore the application of micro ATR-FTIR spectroscopic imaging to cultural heritage samples from the collaborative partners, The National Gallery London and the British Museum, and to develop aspects of the methodology.

Characterisation of the materials of cultural heritage collections is vital in understanding how they were made and used, their conservation history, origin and mechanisms of material decay, and how deterioration has affected appearance. Conventional FTIR microscopy is of proven value in this field, but as samples typically need to be in the form of tiny powdered scrapings, precise information about location of materials within the microstructure of an object is lost. Analysis of samples prepared as cross-sections is useful since the distribution of materials within the layer structure reflects the working practices of the artist/maker and helps to differentiate between original and later materials, as well as deterioration products. Reflectance FTIR imaging has been used for this purpose but the spatial resolution is generally not sufficient. The higher spatial resolution achieved with ATR-FTIR imaging has transformed the appeal of FTIR techniques for this type of sample, and has the potential to become routine for the simultaneous characterization of organic and inorganic materials directly on cross-sections.

Congratulations to Sakoto for her winning poster!
