Sentences with phrase «magnetic nanoparticles heat»

When exposed to a magnetic field, injected magnetic nanoparticles heat up and cause neurons carrying a gene for heat sensitivity to fire (shown in yellow, white, green and light blue at right).

Not exact matches

Arnd Pralle, a physics researcher at the State University of New York at Buffalo, has developed a technique for employing magnetic fields to heat up nanoparticles that have been implanted in neurons.

The magnetic nanoparticles are excited by the applied field and begin to get hot, heating and potentially destroying the surrounding cancer tissue.

Mice with cancer were placed in an alternating magnetic field, causing nanoparticles injected into a tumor to give out heat and destroy it.

Once the virus infected neurons with the heat - sensing gene, the researchers injected magnetic nanoparticles into the same brain cells.

When they exposed the mouse to a magnetic field, the nanoparticles warmed up, and the now heat - sensitive neurons fired.

A combination of iron - oxide nanoparticles and an alternating magnetic field, which together generate heat, have activated an immune system response to tumors in mice according to an accepted manuscript by Dartmouth - Hitchcock Norris Cotton Center researchers in the journal Nanomedicine: Nanotechnology, Biology and Medicine released online on February 24, 2014.

Previous cancer studies had shown that by injecting tumors with magnetic nanoparticles made of iron oxide — «essentially rust, with well - tuned magnetic properties,» Anikeeva says — then exposing them to rapidly alternating magnetic fields, excited nanoparticles can be used to heat and destroy cancer tumors while leaving surrounding, healthy tissue intact.

Researchers use heated magnetic nanoparticles to manipulate nerve cells and control simple behavior in nematodes

Before injecting nematodes with magnetic nanoparticles, the scientists first coated the manganese — iron nanoparticles with polyethylene glycol, a molecule that targeted the particles to the mucus layer of the amphid region (an opening near the nematode's mouth that hosts the nerve cells involved in the heat avoidance reflex).

«It's well known that you can inject magnetic nanoparticles and heat them up, so for me the nematode study is not as elegant as the earlier tests,» Dobson says.

A team of biophysicists from the State University of New York (S.U.N.Y.) at Buffalo used magnetic nanoparticles to control heat - activated protein gates called ion channels embedded in the membranes of nerve cells, allowing the researchers to stimulate a simple reflex in nematode worms at will.

A University of Manitoba physicist is part of an international research team developing a cancer treatment method that uses magnetic nanoparticles to kill tumours with heat.

The team used iron oxide for the core of the nanoparticles, which not only enables the team to use them for magnetic resonance imaging, but opens up possibilities in remote guidance and localized magnetic heating to hasten the breaking up of the clots.

In the system, nanoparticles injected into the brain convert a gentle, external magnetic field into heat, which triggers heat - sensitive ion channels that have been genetically engineered into neurons.
