New research from University of Pennsylvania engineers shows a way to coat an iron-based contrast agent so that it only interacts with the acidic environment of tumors, making it safer, cheaper and more effective than existing alternatives.
Researchers have developed a method to chemically etch patterned arrays in the semiconductor gallium arsenide, used in solar cells, lasers, light emitting diodes (LEDs), field effect transistors (FETs), capacitors and sensors.
Researchers have shown how arrays of tiny "plasmonic nanoantennas" are able to precisely manipulate light in new ways that could make possible a range of optical innovations such as more powerful microscopes, telecommunications and computers.
Mechanism of action of drugs in body cells becomes transparent - the LIMON 3D microscopy (LIght MicroscOpical Nanosizing) of Prof. Dr. Dr. Christoph Cremer opens new possibilities for pharmaceutical research. 3D molecular complexes so-called biomolecular machines, targets of drugs can thus be studied in vivo.
The Japan Synchrotron Radiation Research Institute, Tokyo Institute of Technology, the National Institute for Materials Science, and Kyoto University confirmed for the first time in the world that it is possible to achieve ultra-high speed switching in a time of 200 nanoseconds with a new piezoelectric thin film which possesses nanodomains.
Scienists have investigated theoretically the mechanism of hyperthermic potentiation of cancers using magnetic nanoparticles, which enables selective heating of hidden micro cancer tissue, and clarified the fact that the nanoparticles under large magnetic fields form unique oriented states, depending respectively on subtle differences in their local environment in the cancer tissue and consequently affect the optimum heating conditions.
