Abstract:
PURPOSE: An artificial nerve networking system and a method therefor are provided to selectively detect, analyze, transfer, and stimulate a damaged nerve signal. CONSTITUTION: An artificial nerve networking system comprises a first nerve conduit(100), a second nerve conduit(200), and an artificial nerve network part(300). The first nerve conduit is connected to one side end of damaged nerve. The second nerve conduit is connected to the other side end of the damaged nerve. The artificial neural network part restores the function of the damaged nerve. The first nerve conduit and second nerve conduit comprise a support, a hollow channel, an electrode layer, and an outer electrode.

Abstract:
PURPOSE: A microfluidic device for optically analyzing biochemical samples is provided to enable a user to easily carry the device with the small size, and to economically produce the device. CONSTITUTION: A microfluidic device(1) for optically analyzing biochemical samples comprises the following: a U shaped micro channel(20); an inlet(10) for inserting the samples into the micro channel; an outlet(30) for discharging the samples from the micro channel; and a partition wall(40) located in between left and right flow paths of the micro channel.
Abstract:
A microchannel chip for continuously diluting a solution and a diluting method thereof are provided to effectively transmit a signal between cells by using an outlet as a cell culturing space. A microchannel chip for continuously diluting a solution comprises a dilution material inlet, a first channel(1), a sample inlet, and a second channel(2). The first channel connected to the dilution material inlet passes a dilution material therethrough, and has plural branch points where the dilution material is diverged. The second channel coupled to the sample inlet passes a sample therethrough, and includes plural junctions where the dilution material flows in. The branch points and the junctions are connected by a branch channel one to one. An outflow channel(4) is connected at the next point of each junction in the second channel in order to discharge dilution liquid wherein the sample is diluted by the dilution material to an outlet.
Abstract:
본 발명은 줄기세포 분화를 위한 것으로, 균일한 크기와 모양의 배아체(EB, embryoid body) 생성과 생성된 EB의 성장 및 그 후의 세포 분화를 할 수 있도록 하는 세포 배양 방법 및 장치에 관한 것이다. 본 세포 배양 장치는 1.0 내지 2.6mm의 작은 지름을 갖고 상하면이 열려진 원통형 용기 (cylinder)에서 EB (embryoid body)를 균일하고 빠르게 형성시키며, 형성된 배아체의 성장을 위한 배양 용기의 하부 바닥은 미세 다공막층(micro-pore layer)이 접합되어 있어서, 형성된 EB (embryoid body)는 밑바닥으로 통과되지 않는 반면 하부로부터의 배양액의 공급은 원활히 이루어지도록 하며 장시간 동안 세포배양을 할 수 있다. 본 발명을 이용하면 신속하고 정량적으로 배아체 형성 및 세포 분화를 진행 할 수 있다. 배아체, 배아체 형성층, 배양 용기층, 미세 다공막층, 줄기세포, 분화
