Analytical ChemistryREVIEW worth noting that conference proceedings are available online for important meetings in this field including the International Symposium on Human Identification (aka the "Promega meeting") (http://www.promega.com/geneticidproc/) and the International Society of Forensic Genetics (ISFG) (http://www. isfg.org) meetings. Volume 13 of Progress in Forensic Genetics, which contains the proceedings of the ISFG meeting held in Buenos Aires, Argentina, in September 2009, includes 250 brief articles covering current research on all aspects of forensic DNA typing. 2 Short tandem repeat (STR) typing of autosomal markers with fluorescence-based detection is now almost universally used in forensic DNA laboratories worldwide. 3 Reduced-size STR, or miniSTR, assays are being developed for improved recovery of information from badly damaged DNA templates. Low level DNA and samples containing mixtures continue to present challenges for forensic analysts. A large portion of the literature involves reporting STR allele frequencies from various populations. However, limited space in this review prevents a summary or description of the many population studies performed in 2009 and 2010.Single nucleotide polymorphisms (SNPs) continue to be explored as potential supplements to STR markers already in use but will probably not replace STRs in the near future. Information on uniparental lineage markers from the Y-chromosome and mitochondrial DNA continues to accumulate in the literature. These lineage markers are also widely used for human evolutionary studies and genetic genealogy. The availability of commercial kits for Y-STR amplification has enabled more widespread usage of these important male-specific markers in forensic DNA laboratories. A number of X-chromosome STRs are also being investigated. Nonhuman DNA plays a useful role in many forensic investigations. Tests have been developed for plant and animal DNA testing to associate victims or suspects to crime scenes.National DNA databases collectively house millions of STR profiles around the world. With the demonstrated success of linking previous offenders to unsolved crimes they have committed, new legislation is expanding the number of samples that will be going into DNA databases of the future. In December 2010, the United States exceeded 9.5 million DNA profiles in the National DNA Index System of the FBI Laboratory's Combined DNA Index System (CODIS). The United Kingdom has over four million STR profiles in their national DNA database, which represents a significant portion of their active criminal population.Automation of laboratory techniques and data interpretation with expert systems has become increasingly important with the large numbers of DNA samples that need to be examined. Forensic DNA testing also aids missing persons investigations and identification of mass disaster victims albeit with some extra issues unique to kinship and parentage analysis. At the end of the forensic DNA analysis section, we also list relevant papers on interpretat...

“…In this approach, cross-section samples are mounted in a polyester resin, polished to reveal the paint stratigraphy, and then analysed using a variety of techniques. For example, cross-section analysis is oen accomplished using optical microscopy, 16 attenuated total reection Fourier transform infrared spectroscopy (ATR-FTIR), 14,[17][18][19][20] normal Raman scattering (NRS), 14,[21][22][23][24][25] visible light imaging microspectroscopy (VISimaging), 26 and secondary ion mass spectrometry (SIMS). 27 Although these approaches, sometimes coupled with energy dispersive X-ray analysis (EDX) or micro-X-ray uorescence (XRF), detect inorganic pigments as well as organic binders, proteins, and lipids, they do not enable the unambiguous identication of natural, organic colorants in cross-sections.…”

The analysis of paint cross-sections can reveal a remarkable amount of information about the layers and materials in a painting without visibly altering the artwork. Although a variety of analytical approaches are used to detect inorganic pigments as well as organic binders, proteins, and lipids in cross-sections, they do not provide for the unambiguous identification of natural, organic colorants. Here, we develop a novel combined surface-enhanced Raman scattering (SERS), light microscopy, and normal Raman scattering (NRS) approach for the identification of red organic and inorganic pigments in paint cross-sections obtained from historic 18th and 19th century oil paintings. In particular, Ag nanoparticles are directly applied to localized areas of paint cross-sections mounted in polyester resin for SERS analysis of the organic pigments. This combined extractionless non-hydrolysis SERS and NRS approach provides for the definitive identification of carmine lake, madder lake, and vermilion in multiple paint layers. To our knowledge, this study represents the first in situ identification of natural, organic pigments within paint cross-sections from oil paintings. Furthermore, the combination of SERS and normal Raman, with light microscopy provides conservators with a more comprehensive understanding of a painting from a single sample and without the need for sample pretreatment.

“…1 To realise an artefact, the artists in general used a wide range of organic and inorganic products with different purposes and roles. 2 The application of painted films on the surfaces had mainly an aesthetical role but at the same time performed a protective behaviour due to chemical characteristics of the materials, e.g. hydrophobicity, hardness or flatness of the surface.…”

It is known that the physical properties and the conservation rate of a wooden artefact are strictly related to its surface treatment, especially in order to control mechanical and rheological properties and to increase the durability of the wood. The pictorial film of painting forms a structure that, adhering to the wood surface, plays both a protective and an aesthetic role. In order to restore artefacts, it is important to know the original function of the external coating. The aim of this paper is to define the nature and the function of a white coating covering all the surface of a bas relief made by Giacomo Bertesi, one of the most important artists and wood carvers in northern Italy, in the second half of the seventeenth century. Three microsamples were taken from the surface. Micro-Fourier transform infrared and scanning electron microscopy-energy dispersive X-ray spectroscopy analyses were performed to characterise the materials and the different layers.
