Mei developed can be remote-controlled magnetic nanoparticles

United States scientists developed a cell membrane of magnetic nanoparticles, enables scientists to remote control of ion channels, neurons, and even to control animal behavior.

The findings of the recently published in nature magazine · nanotechnology.

Buffalo University research team that developed the magnetic nanoparticles, Nano-size 6 easily spread among the cells.

The researchers first fixed the nano-particles in the plasma membrane, then take advantage of high-frequency magnetic field on its heating, thereby stimulating the cell. In view of this method can be relatively large range evenly stimulate cells, scientists believe that this method will be applied in the human body.

Researchers have proved that this method can open calcium channel, activate neurons by cell culture, and even manipulate tiny nematodes.

When researchers will magnetic nanoparticles fixed online insect mouth and began to climb the nematode just to climb. However, when the scientists will magnetic nanoparticles heated to 34 degrees Celsius, you will be able to control nematodes in the forward and back.

The research group also invented a fluorescent probe, according to the changes of fluorescence intensity, to measurement of nanoparticles is heated to 34 ° c, the fluorescent probe can be said is a Nano-thermometer.

This study has a wide range of applications, such as in cancer treatment, scientists against selected protein or specific organization for remote operations, allowing the development of new cancer therapies.

In addition, in the treatment of diabetes mellitus or remotely stimulate pancreatic cells release of insulin. This method can also be applied to certain insufficient due to stimulating disorders of the nervous system.

Scientists said this is very important, since this method only heating membrane and cell temperature does not change, so do not lead to cell death.

Through this method, scientists can use magnetic field in the in vitro and in vivo stimulates cells to help understand the cell signaling networks, as well as the behavior of the control animals.
