<p> The limitations of chemical synthesis can be overcome by nanoparticles produced by magnetotactic bacteria. The prototypical Magnetospirillum (M.) gryphiswaldensee exhibits octahedral magnetite (Fe3O4) nanocrystals with a maximal size of 50 nm. Shape and size can be controlled by genetic engineering leading to recombinant magnetic nanoparticles from 20 nm to 150 nm in diameter. Particle sizes in the transition area in between supra- and ferrimagnetism are difficult to achieve chemically or other methods. <p> Based on the unique properties the tailor made nanocrystals produced by bacterial magnetosomes several applications can be developed. In hyperthermal treatments, a high specific energy transfer can be achieved. Likewise, magnetic separation will benefit from the high specific magentization capacity and will improve the process. <p>

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
