Liposomes, Magnetic Nanoparticles and Photosensitizers Combined to Fight Cancer

By combining, in a liposome, magnetic nanoparticles and photosensitizers that are simultaneously and remotely activated by external physical stimuli (a magnetic field and light), scientists at the Laboratoire Matière et Systèmes Complexes (CNRS/Université Paris Diderot) and the Laboratoire Physicochimie des Electrolytes et Nanosystèmes Interfaciaux (CNRS/UPMC), obtained total tumor regression in mice.

Magnetic Nanoparticles Open the Blood-Brain Barrier to Deliver Molecules to the Brain

Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine.

Theoretically, Direction of Spin of Nanoscale Magnets Can Be Controlled Remotely

In the eyes of physicists, magnetic molecules can be considered as nanoscale magnets. Remotely controlling the direction in which they rotate, like spinning tops, may intuitively be difficult to achieve. However, Russian physicists have just demonstrated that it is theoretically possible to do so. They have shown that a change of direction in the circular polarisation of an external magnetic field leads to a change in the direction of the mechanical rotation of the molecule.

New Research into Using Magnetic Nanoparticles in Localised Brain Tissue Stimulation

MIT researchers have created a technique to stimulate brain tissue using injected magnetic nanoparticles and external magnetic fields.

Diamond Nanocrystal Helps Map Magnetic Field Around a Micro-Particle

Measuring faint magnetic fields is a trillion-dollar business. Gigabytes of data, stored and quickly retrieved from chips the size of a coin, are at the heart of consumer electronics. Even higher data densities can be achieved by enhancing magnetic detection sensitivity---perhaps down to nano-tesla levels.

Scientists Develop Ultrathin Magnetic Sensor with Extraordinary Mechanical Robustness

Scientists from Germany and Japan have developed a new magnetic sensor, which is thin, robust and pliable enough to be smoothly adapted to human skin, even to the most flexible part of the human palm. This is feeding the vision to equip humans with magnetic sense.

Selective Creation of Magnetic Nanovortices Using Magnetic Fields

"With the help of magnetic fields, we can selectively create the magnetic nanovortices, then give them a shove so that they are deflected out of their equilibrium position", explains Dr. Felix Büttner, who pursued this research as his Ph.D. project. "We were then able to very precisely track how these skyrmions, as these special nanovortices are called, return to their rest position", Büttner explains further.

Researchers Successfully Switch Tiny, Magnetic Structures Using Laser Light

Researchers at the Paul Scherrer Institute (PSI) have succeeded in switching tiny, magnetic structures using laser light and tracking the change over time. In the process, a nanometre-sized area bizarrely reminiscent of the Batman logo appeared. The research results could render data storage on hard drives faster, more compact and more efficient.

Researchers Endeavor to Create Faster Computers Using “Spin” of Electrons on Nanomagnets

Computers are basically machines that process information in the form of electronic zeros and ones. But two MIT professors of materials science and engineering are trying to change that.

Iron-Oxide Nanoparticles Can Successfully Detect Ovarian Tumors In Vivo

Google’s latest search initiative isn’t taking place online, but in the human body instead. On October 28, The Wall Street Journal reported that the Internet giant wants to design tiny magnetic particles to patrol the body for signs of cancer and other diseases. Google said its nanoparticles, less than one-thousandth the width of a red blood cell, would seek out and attach themselves to cells, proteins or other molecules inside the body.
