X-ray fluorescence analysis (XRF) is widely used when determining the concentrations of elements in various materials in biological research. Current review considers the achievements related to the features of the XRF method. X-ray fluorescence analysis in most cases is a non-destructive method that has proven its potential for measuring the concentrations of elements with a high atomic number Z in organs and tissues in vivo. The main areas of its application in biology and medicine are content determination of basic and toxic elements in plants, samples of bones, teeth, hairs, nails and tissues of vital organs, body fluids such as blood, serum, plasma, saliva, urine, etc. Usually, these studies are part of applied programs that include environmental and metabolic analyses of the population, including the influence of professional factors. The advantages of XRF are also discussed with regards to biological materials. It is noted that the form of the element in the sample practically does not affect the analysis result. In recent years, several new XRF spectrometers models have been designed, where polycapillary lenses and half lenses are used as collimating systems. This is important in the case of in vivo application of X-ray fluorescence determination of certain elements in bones and tissues. The dynamic development is typical for detectors with thermoelectric cooling. Variants of preparation of biological materials for analysis are discussed (grinding, dry or wet ashing, acid decomposition, use of suspensions in the case of XRF with TIR). The results of evaluating the interelement effects for XRF of materials of plant origin, including herbs, spices, apple leaves, birch and tomato leaves, tea, wheat, rye, rice, oatmeal, flax flour, beans, ground, and instant coffee are presented. Examples of the use of XRF in various types of forensic research are considered: poisoning, counterfeiting of drugs and food brands, dental implants, identification of remains. The review presents examples of the participation of Russian X-ray physicists in solving the problems under consideration. The list of references is 400 papers, mainly including the publications of the last 20 years.

“…Portable systems are available for point-ofcare measurements. A recent application involved classification of nail polish samples based on Ca and Ti amounts (Shimamoto et al 2013). A filter paper was used as surface support and samples were irradiated for 20 s with data processing by principal component analysis (PCA), without requiring sample preparation or using of chemicals.…”

Green Analytical Chemistry (GAC) is a research field that seeks for more sustainable analytical approaches to minimize the toxicity and amounts of wastes without hindering the analytical performance. This is a trend in Analytical Chemistry worldwide and because of the diversity of innovations on this subject, Brazil stands out as the third in the list of the main contributors to GAC, with ca. 11.2% of the published articles. Significant innovations and interesting applications in several fields have been presented and Brazil is continuously moving from Chemistry to Green Chemistry also in the Analytical Chemistry field. Selected contributions for sample preparation, spectro-and electroanalysis, separation techniques, chemometrics, and also procedures for point-of-care measurements are critically reviewed.

“…In addition, it has direct application in forensic science (MISRA et al, 1992. MURPHY et al, 2012TERRA;BUENO, 2013), as in the analysis of cosmetic residues in crime scenes. Elemental characterization may be verified by analytical methods like X-ray fluorescence spectroscopy.…”

Nos dias de hoje, produtos cosméticos desempenham um importante papel na vida de quase todas as pessoas. Homens e mulheres dedicam muito tempo, recursos e esforços para cultivar a higiene pessoal e a melhor aparência possível ao longo de suas vidas. Um dos tipos de cosméticos mais utilizados é a sombra para os olhos. A fluorescência de raios X (XRF) é uma técnica bem estabelecida, conhecida por sua capacidade de identificar e quantificar espécies inorgânicas de maneira simples, rápida e não-destrutiva, no entanto, não é amplamente utilizada em análises de produtos cosméticos. A fim de se mostrar a potencialidade da técnica, fluorescência de raios X por dispersão em energia portátil foi empregada na quantificação de elementos inorgânicos em 40 sombras para os olhos brasileiras. Foi possível identificar e quantificar os elementos Cl, K, Ca, Ti, Cr, Mn, Fe, Cu, Zn e Bi. Utilizando a análise de componentes principais, foi possível distinguir os diferentes fabricantes. A metodologia de fluorescência de raios X associada à análise de componentes principais provou ser uma ferramenta valiosa para a discriminação e caracterização de produtos cosméticos.
