  • METHOD OF CELL CULTURE OBSERVATION, CARBON SUBSTRATE FOR CELL CULTURE OBSERVATION, AND METHOD FOR MANUFACTURE THEREOF
    Publication number: 20060194312
    Abstract: The invention provides a substrate suitable for cell culture observation and a method of observation using the same. Crystalline carbon such as a graphite powder is mixed into a thermosetting resin such as a furan resin, and the mixture is molded in the shape of a sheet and carbonized to produce a carbon substrate; then, a cell is made to adhere to the carbon substrate, and the cell is caused to proliferate on the carbon substrate and observed using a microscope.

  • Carbon microrod and method of producing the same
    Patent number: 6838175
    Abstract: A carbon microrod that holds a fine object by chemically adsorbing the object on the surface to make a dynamic measurement possible. An organic substance that leaves, after firing, glassy carbon that hardly becomes graphite, such as a chlorinated vinyl chloride resin, is mixed with a fine graphite powder having an average particle size of 1 ?m, and the mixture is extrusion molded with a die having a diameter of 50 ?m; the molded article is fired to give a carbon microrod comprising glassy carbon and crystalline carbon.
