Sentences with phrase «injected magnetic nanoparticles»

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

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).

«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.

Not exact matches

One promising idea, known as magnetic hyperthermia, involves injecting minuscule «nanoparticles,» basically microscopic lumps of iron oxide or other compounds, into tumors to make them magnetic.

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

Now, a study in mice points to a less invasive way to massage neuronal activity, by injecting metal nanoparticles into the brain and controlling them with magnetic fields.

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.

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).

In looking to improve on these current methods, scientists from Houston Methodist Research Institute loaded magnetic nanoparticles with tPA, the idea being that the drug wouldn't be broken down so quickly once injected.

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.
