The present invention relates to a method and kit of detecting a target material using an aptamer, and more particularly to a method and kit for detecting a target material, in which a sample and a second aptamer are added to a first aptamer immobilized on a solid phase so as to form a bond sandwiched between the first aptamer, the target material and the second aptamer, to an FET sensor-based method and kit for detecting a target material, and to an AAO sensor-based method and kit for detecting a target material. The inventive method for a target material using an aptamer can detect even low-molecular-weight materials which were difficult to detect in the prior art, thereby enabling detection of disease-related metabolites, environmental pollutants and food toxins in solutions. In addition, the detection method of the present invention is a direct and simple method and is highly cost-effective, because it uses the aptamer which can be consistently reproduced and can be produced at low costs. Thus, the present invention is very useful.

The present invention relates to a method of differentiating mesenchymal stem cells or adult stem cells into nerve cells by treating the mesenchymal stem cells or the adult stem cells with an electromagnetic field having a high intensity of 100 to 1,500 mT and a low frequency of 0.01 to 100 Hz. The present invention also relates to a medical device to which the method is applied. The method of differentiating nerve cells by using a magnetic field, and a composition according to the present invention induce the differentiation of adult stem cells into nerve cells by using a low-frequency, high-intensity electromagnetic field, so that nerve cells or neural stem cells can easily be differentiated through only electromagnetic field treatment in a short time.
