Atomic Spectrometry Update: review of advances in the analysis of clinical and biological materials, foods and beverages

Abstract

This review discusses developments in elemental mass spectrometry, atomic absorption, emission and fluorescence, XRF and LIBS, as applied to the analysis of specimens of clinical interest, foods and beverages. Sample preparation procedures and quality assurance are also included.

Ultra-trace element analysis of human follicular fluid by ICP-MS/MS: pre-analytical challenges, contamination control, and matrix effects

“…These studies are summarized in Table 3 using a style similar to that adopted by Atomic Spectrometry Updates for the analysis of clinical and biological materials. 28 The geometric mean values (n=197) for Cu, Sr and Zn reported in this study were similar to those reported by most other studies. Values for Se found here were most similar to those reported by us previously using SF-ICP-MS 14 along with data reported by Nanto et al, 4 and Ozkaya et al,.…”

Rhenium (I) Complexes as Probes for Prokaryotic and Fungal Cells by Fluorescence Microscopy: Do Ligands Matter?

“…Nevertheless, overall limitations of fluorescence microscopy, as an imaging technique, include low resolution to approximately half the wavelength of the light involved in the experiment, and the limited depth of tissue penetration of the light used. This limits visible light fluorescence microscopy to sample depths of a few millimeters and near IR microscopy to a few centimeters (Li et al, 2017; Taylor et al, 2018). For these reasons, it is necessary to develop new and improved luminescent fluorophores, suitable to be used with fluorescence microscopy.…”

Feasibility of microwave‐induced combustion combined with inductively coupled plasma mass spectrometry for bromine and iodine determination in human nail

“…Inductively coupled plasma mass spectrometry (ICP-MS) has emerged as one of the most sensitive and selective analytical techniques for trace elemental analysis in biological samples, enabling high detectability even for small amounts of samples. [1][2][3][4][5] Multielemental capability associated with the conventional nebulization system assures a fast, easy, and efficient sample introduction into the equipment using a minimum amount of solution. Among chemical elements in biological samples, bromine and iodine have received special attention in recent years.…”

“…Biological samples obtained by non-invasive collections such as hair, saliva, urine, and nail are being slowly proposed as biomarkers by the scientific community. 5,13,14 The use of non-invasive samples to overcome the disadvantages of the blood analysis may become the future for nutritional, environmental, medicinal, and other assessment fields. 5,13,14 In some cases, the higher stability and the possibility to reflect long-term exposition make the analysis of hair and nails more attractive than that of urine and saliva.…”

[13][14][15] Parts of the chemical elements are metabolized, and the analysis of biological samples can help us understand the metabolic routes and establish some relationships among chemical elements, some diseases, and environmental contamination.…”
