PROBLEM TO BE SOLVED: To provide a carbon porous body having a large pore capacity and a large specific surface area, and suitable for the diffusion of an adsorbed substance to the inside, and to provide a production method therefor. SOLUTION: The method for producing a carbon porous body comprises: a step where a cage type silica porous body and a carbon source are mixed; a step where the obtained mixture is heated; and a step where the cage type silica porous body is removed from the reaction product. The cage type silica porous body includes: a silica skeleton; a plurality of pores formed by the silica skeleton, and a channel formed of the silica skeleton and coupling the plurality of pores each other. The plurality of pores are three-dimensionally regularly and symmetrically positioned, and the diameter d 1 of the plurality of pores and the diameter d 2 of the channel satisfy the relation of d 1 >d 2 . The cage type silica porous body and the carbon source are mixed in such a manner that the molar ratio (C/Si) between the silicon (Si) in the cage type silica porous body and carbon (C) in the carbon source satisfies the relation of 0.8 COPYRIGHT: (C)2006,JPO&NCIPI
摘要:
A sensor apparatus and associated method for sensing and monitoring specific binding of analyte to an immobilized binding layer are disclosed. The apparatus preferably comprises an automatic critical angle refractometer having a linear scanned array and an optical system for illuminating a portion of the array, which illumination depends upon the refractive index of the binding layer deposited on an optically transparent element. The apparatus further includes a flow cell for bringing the analyte in contact with the binding layer. The apparatus also includes a computer for receiving and processing refractive index data from the critical angle refractometer during the reaction between the analyte and the layer, which computer may be peripherally connected to the refractometer or enclosed within the refractometer housing. A preferred sensing method of the present invention generally comprises providing a critical angle refractometer generating light impinging upon the immobilized binding layer, contacting the binding layer with a contacting phase, measuring the critical angle of total reflection, which measurements are indicative of the presence or absence of interactions between the analyte and the binding layer.
