This very small nano cells probe, it can put inside the cells, monitoring cells is normal play physiology function. The detection device to help diagnose disease and test drug effect.
The university of Edinburgh researchers in the academic journal ACS nano "report, said the probe is in the tiny particles of gold elements on added some special molecules made of, only 130 nanometres in diameter. Will probe into inside the cells, with a bunch of special laser irradiation cell group weaving and by receiving, analysis the probe reflected light, can test cells in the internal environment namely changes, which concluded that cells work.
The researchers colin Campbell said, cell activity like clock running bioelectricity as have the law, if the abnormal bioelectricity changes, cells may appear lesions. Therefore, the nano detector can be used to help in the diagnosis Parkinson's, alzheimer's and other diseases. In addition, it also can be used to test drug effect, evaluation after drug use the response of the cells.
According to introducing, the researchers in the lab has cells to cultivate in this detector experiment, the results show that it is harmless to cells, do not affect the normal cell physiology function. Next, the researchers will human clinical trials, in a real human body to test it in the environment.
People think, nano cells will in future detector in the medical field go a long way.
