Report from the Frontiers in Biomagnetic Nanoparticles Meeting in Telluride 2015

July 22, 2015

Jennifer Andrew, Jeffrey Anker and Thompson Mefford organized now already for the 4th time the Frontiers in Biomagnetic Nanoparticles meeting. It took place in Telluride, Montana, U.S.A. from June 23-25, 2015, a wonderful location high in the Rockies (2590 m above sea level!). With 80 participants, this meeting is smaller than its "twin meeting", the International Conference on the Scientific and Clinical Applications of Magnetic Carriers, but it features just as high-standing talks in the (odd) years between the larger conference.

This time, we had an especially interesting time during discussions about how magnetic hyperthermia works, why it seems to work even without (measurable) heat production, and if we actually should rename the effect to thermophoresis. Especially Tim St. Pierre, his student Michael McPhail and Julian Carrey brought up many interesting points, and we are sure that the discussions will go on during next year's Magnetic Carrier meeting.

Another interesting area that quite a few talks were discussing was the use of magnetic nanoparticles as T2 (and T1) contrast agents in Magnetic Resonance Imaging. Especially the group from NIST Boulder gave some interesting talks, while the shape anisotropy was also mentioned as very important. Jin Xie very nicely reviewed the area and their recent developments and showed how Fe5C2 nanoparticles might replace some of the Gd-based agents in the future.

The next Frontiers of Biomagnetic Particles meeting will take place in 2017 again. Make sure you write it into your calendar!

Successful Conference in Timisoara - June 25-26 , 2015

July 17, 2015

The Magnetic Fluids & Applications meetings are organized in Timisoara since 1980 by the Politehnica University of Timisoara and the Timisoara Branch of the Romanian Academy. The workshop Multifunctional nanoparticles, magnetically controllable fluids, CNISFC_Siglacomplex flows, engineering and biomedical applications held in the period 25-26 June, 2015 with 16 oral presentations, among them 3 keynote lectures and 5 invited talks, proved to be an excellent opportunity for scientists, representatives of industry, master and PhD students from Germany, Russia, Slovakia, Hungary and the host country Romania to have very stimulating discussions towards cooperation for scientific and technological progress in the field.

The abstracts of oral and poster presentations may be seen here.

Latest Status on MPI Research

July 15, 2015

MPI is a tomographic imaging technique that detects the magnetic properties of iron-oxide nanoparticles injected into the bloodstream to produce 3D images. The new technology, invented by Philips, and first introduced in a 2005 Nature paper, gave rise to a new era in biological imaging. The first commercial machines to do Magnetic Particle Imaging are now available from Bruker. Check out their assessment of the technology (and advertisement) on their website:


The most recent international meeting about MPI was in Istanbul from March 26-28, 2015. And the next meeting will be in Lübeck, Germany, from March 16-18, 2016. Check out details about earlier and upcoming MPI meetings here:

World Record Speed of a Maglev Train: 603 km/h

April 21, 2015

The Central Japan Railway company reports that its magnetic levitation bullet train topped 603 km/h on Tuesday during a test run along a length of test track in the Yamanashi prefecture. This was enough to break its own 12-year-old, 361 mph world record set back in 2003. The train reportedly carried 29 engineers during its run.

Unfortunate is the fact that normal passengers will likely never be able to experience these exhilarating speeds -- unless something goes horribly wrong. The rail company plans to limit the trains to a pokey 313 mph for regular service when they come online in 2027. But even at these speeds, commuters could make it from Tokyo to Nagoya in about 40 minutes (less than half the time today's fastest bullet trains require). The company even has aspirations to export this technology to America -- specifically as a high-speed rail line running between New York City and Washington DC.

Use of Moessbauer Spectroscopy for Careful Assessment of Magnetic Nanoparticles

March 26, 2015

The use of Mossbauer spectroscopy is a simple and direct way to determine the amounts of magnetite and maghemite in an otherwise unknown sample. Quentin Pankhurst et al wrote a nice paper about how to use it and determine magnetite/maghemite weighting directly from the mean isomer shift of the total spectrum, which means that one can apply a simple model-independent curve-fitting methodology. Compared to the older way of using Moessbauer, this takes an awful lot of the work out of the process.

How to Reliably Measure the SAR of Magnetic Hyperthermia Materials

March 26, 2015

Wildeboer, Southern and Pankhurst published recently a paper about the reliable measurement of specific absorption rates and intrinsic loss parameters in magnetic hyperthermia. They also carefully reviewed how to cope with non-adiabatic measurement conditions. This paper might very useful for the novice and more experienced user, as they went pretty thoroughly through the methodologies, and have tried to make some recommendations for both the measurement procedure, and the analysis method, that anyone will be able to follow.

Magnetic Carrier Meeting 2014

February 15, 2015

Our already 10th International Conference on the Scientific and Clinical Applications of Magnetic Carriers took place in Dresden, Germany from June 10-14, 2014. It was a wonderful gathering of more than 330 participants from 41 countries, where we discussed all the different aspects of magnetic nanoparticles and microspheres, how they can be made, used and applied in new and ever more fascinating ways!

Check out all the details at


The research discussed at the meeting has now been published in full-size peer-reviewed papers in the Journal of Magnetism and Magnetic Materials (JMMM). Check it out here.
