  • Cell-based transparent sensor capable of real-time optical observation of cell behavior, method for manufacturing the same and multi-detection sensor chip using the same
    Patent number: 8926812
    Abstract: The present invention relates to a cell-based transparent sensor capable of the real-time optical observation of cell behavior, to a method for manufacturing same, and to a multi-detection sensor chip using same. More particularly, the present invention relates to a cell-based transparent sensor capable of the real-time optical observation of cell behavior, to a method for manufacturing same, and to a multi-detection sensor chip using same, wherein the sensor can sense the ionic concentration of an electrolyte in accordance with the variation in the metabolic activity of cells using an ion-selective field effect transistor (ISFET) sensor and an electrochemical sensor, and the sensor is made of a transparent material which enables real-time observations of optical phenomenon for measurement of cell behavior.

  • CARBON NANOTUBES SERVING AS STEM CELL SCAFFOLD
    Publication number: 20090148417
    Abstract: The present invention relates to a scaffold for transplanting a stem cell comprising a carbon nanotube without cytotoxicity, and a composition for stem cell therapy comprising (a) a stem cell; and (b) a carbon nanotube serving as a stem cell scaffold without cytotoxicity. The scaffold for transplanting stem cells comprising carbon nanotubes show excellent effects without cytotoxicity on networking between differentiated stem cells and tissues present in transplantation sites, thereby showing significant cell therapy efficacy.
