The new nanoscale thermometer can be used to measure living cells

A tool developed initially for a quantum computer, are now able to measure temperature changes within a living cell. The technology USES tiny diamond crystals or 'nano diamond' quantum effects, detection of degrees per thousand of temperature change. With their help, the researchers can also use laser heating some specific part of the cell. 'Now, we have a tool in cell level control temperature, temperature changes at the same time also can study how to deal with biological systems. 'Said Peter Maurer Harvard University physicist, he involved in the experiment. The related research results recently published in the journal nature. This kind of magnetic probe small fluctuations are very sensitive to temperature. Through the probe will be used for accurate thermometer, researchers began its potential disadvantage into advantage. Now, Maurer and his colleagues have this kind of tool used in biology.

the researchers use nanometer thin lines will be diamond crystals into human embryonic cells. Then, they use the green laser irradiation to the cells, resulting in nitrogen impurity a red fluorescence. Research team is using the fluorescent molecules are temperature of a body, but the thermometer are sensitive than those of Harvard University at least 10 times. Maurer says it can detect only 0. 05 kelvin temperature fluctuations. Researchers also noted that the technology still room for improvement, because on the outside of the cell, the sensitivity of the tiny device can already amounted to 0. 0018 degrees kelvin.
