Welcome to the May issue of EVISA's Speciation Newsletter !
Biological functions of metals are not only specified by the element itself, but also by its chemical form and by its organ, cell and subcellular location. In order to study such biological functions therefore analytical methods should provide information about speciation and localization. Speciation analysis and bioimaging are able to provide such information. A very important aspect for both methodologies is quantification. Quantitative imaging is a prerequisite for the correct interpretation of the concentration data displayed in the image. External calibration against standard materials is an often applied approach for quantification. Unfortunately, reference materials, with certified concentrations and homogeneous distribution within a surface or a sample volume of a biological material are not available. Researchers from the University of Münster come up with a quantification method for bioimaging by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The new method is based on Isotope Dilution Analysis, that can overcome some of the problems (see the news below).
Bioimaging with the aid of LA-ICP-MS was also used to study the distribution of gadolinium in the brain of patients who received serial injections of gadolinium based MRI contrast agent for enhanced medical diagnostic imaging. Their results show that gadolinium depositions in the brain are restricted
to blood vessel walls, while the neuropil is spared and apparent
cellular reactions are absent.
The methodology of laser ablation based bioimaging and its application for biological and clinical application will be discussed during a workshop taking place in Münster next week.

EVISA is keeping you updated with what is going on in speciation analysis. In this section you will find news about the most current research results, about trends, legal issues and information from manufacturers in the field of speciation analysis.
With all the links to further information and publications the News archive is a valuable collection of "hot topics" in speciation analysis. We continuously update even former news with new links and information so that all news are actual all the time.
Gadolinium-based contrast agents induce gadolinium deposits in cerebral vessel walls
German researchers specified the distribution of gadolinium in the brain of patients who received serial injections of gadolinium based MRI contrast agents with a spatial resolution in the low-µm range and also explored any potential pathological tissue changes caused by gadolinium deposits.
