Abstract: The problem is solved by including: a display section (2) for displaying information; a pressure sensor array section (4) constituted by a plurality of pressure sensors (3) arranged in a matrix form; and a control section (5) for controlling a speed of page turning of information to be displayed, the pressure sensor array section (4) outputting a pressure change to the control section (5) together with a position of the display device (1), the control section (5) carrying out page turning at a speed corresponding to the position.

Abstract: A method of fixing a low-molecular compound to a solid-phase support, by bringing a solution containing a low-molecular compound into contact with a solid-phase support having a photoreactive compound bonded to the surface, evaporating the solution containing a low-molecular compound to dryness, in the state of being in contact with the solid-phase support, and irradiating the solid-phase support with light to form a covalent bond between the photoreactive compound and the low-molecular compound. This fixing method enables a low-molecular compound to be fixed to a solid-phase support without the aid of a functional group.

Abstract: A method of label-free observing of any interaction between biomolecule and substance immobilized on a metal substrate, characterized in that the substance is immobilized on the metal substrate by a covalent bond through photoreaction.
