In the collaboration with Institute of Chemical Technology and Analytics (TU Wien) we ran the project on collecting both elemental and molecular information from the very same slice! The methods employed – µXRF for elemental and MALDI for molecular information. The sample on which we tested the workflow could be easily bought on market – chicken feet (phalanx section was measured). Yummy!
The project is described in the paper “Multimodal imaging of undecalcified tissue sections by MALDI MS and μXRF” published by Analyst.
We were once again measuring at BESSY II. From 1.5-7.5. 2017 we measured our samples with a confocal microXRF setup at the mySpot. From 8.5-11-5.2017 we did XANES (X-ray absorption near-edge structure) measurements at the neighboring BAMline.
While being at BESSY II, we were interviewed for the HZB magazine “Lichtblick”. The resulting article can be found here: https://goo.gl/3n33M8 (page 3, in German).
The Seminar Activation Analysis and Gamma Spectroscopy (SAAGAS 26), took place on 19-22 February in TU Wien, Vienna, Austria. Our group from Atominstitut contributed to the Seminar 2 oral presentations, as well as 5 posters – and three of the posters were devoted to biological samples:
- Total X-ray reflection spectrometry of black tea and herbal infusions
- μXRF spectrometer of Atominstitut in bio-imaging application
- Confocal μXRF spectrometer for low to high Z element analysis
We’re very delighted to share, that the talk of Mirjam Rauwolf – “Synchrotron radiation micro XRF analysis of zinc in osteosarcoma tissue” received an award!
In the middle of February we traveled once again to Diamond synchrotron. This time we performed highly-resolved (1 micron!) XRF imaging of bone-cartilage samples. Thanks to the supportive team of B16 beamline, we’re going to visit you again soon!
The team at work:
The XRF-Bone team wishes you a happy new year!
And if your new year’s resolution is to read more papers, check out the early view online version of our newest paper – “Increased zinc accumulation in mineralized osteosarcoma tissue measured by confocal synchrotron radiation micro X-ray fluorescence analysis” which will be published in X-Ray Spectrometry.
Our new paper compares a confocal and a color X-ray camera setup. It will be published in the January 2017 issue of the Journal of Synchrotron Radiation. You can already read it online if you follow this link.
Our new paper was just published as open access in Materials and you can read it here or you can download the pdf version from our publications page.
We will be measuring bone samples at mySpot (BESSY II, HZB, Berlin, Germany) from 12.9 – 25.9.2016 and we are hoping for a lot of new and exciting results.
After the beamtime, we will be attending 66th Yearly Meeting of the Austrian Physical Society (OEPG2016).
Annual Meeting of the Austrian Physical Society (OEPG2016)
You can meet us at our posters during the poster session on Tuesday 27th of September 17:15 – 19:00 (Boltzmanngasse 5, 3rd floor, in front of Josef-Stefan lecture hall). We will present the following three posters:
PT24: Confocal SR-µXRF measurements of increased Zinc accumulation in mineralized osteosarcoma
PT25: Confocal µXRF spectrometer for analysis of 3-dimensional spatial distribution of low to high Z elements
PT26: Total X-ray reflection fluorescence spectrometry analysis of trace elements in tea and herbal infusions
We might be running a little bit late though, as we will be attending the Young-Minds-Session (Tuesday 27th of September from 16:15, Boltzmanngasse 5, 3rd floor, Christian-Doppler lecture hall). A session created for students and as well as laypersons prepared by the ÖPG Young Minds (the representation for students, PhDs and Post-Docs of the Austrian Physical Society). Lectures will be held in German and are free of charge for school classes.
More information about the Young-Minds-Session can be found in the flyer and on the poster below:

X-Ray Microscopy Conference 2016
Thanks to everyone who visited our posters in Chicago!
If you did not have a chance to see our work yet, we will be at the X-ray Microscopy Conference in Oxford – 15th to 19th August 2016.
We will present three posters on Monday 15th from 17:00 to 19:00:
Zinc Distribution In Human Bone: SR-Micro X-Ray Fluorescence Imaging of Osteoporotic Samples (S1-P3-05)
Exploitation of μXRF Spectrometer for Bio-imaging (S1-P3-06)
High resolution imaging of metal localization in cancer cells at the B16 beamline at Diamond.
Denver X-ray Conference 2016
We will be at the Denver X-ray Conference, which will take place in Chicago from 1-5 of August 2016.
During the XRF Poster Session on Tuesday evening (5:00 pm – 7:00 pm in the Michigan Room), we are presenting four posters :
F-62 Increased Zinc Accumulation in Mineralized Osteosarcoma Tissue Measured by SR-μXRF Analysis
F-63 Zn Distribution in Healing Osteoporotic Fractures Measured by SR-μXRF Analysis
F-66 Manganese Distribution in Healthy and Osteoporotic Human Bone
F-67 Elemental Imaging on Biodegradable Orthopedic Implants by μXRF
We hope to see you in Chicago!
