摘要： A chemical substance sensing element 142 for detecting a specific chemical substance included in biological information includes a carbon nanostructure and, because of metal complex or a fluorescent molecule modifying its surface, exhibits substance selectivity and high sensitivity. Of the substances modifying the surface of carbon nanostructures, CoPc reacts with NO and pentane and DAF-2 reacts with NO, as the components contained in the biological information, respectively, and both produce reaction products. The reaction product derived from CoPc changes electric resistance between nodes 154 and 156, and the reaction product derived from DAF-2 generates fluorescence of a specific wavelength when irradiated with excitation light. Therefore, by measuring the change in electric resistance or presence/absence and wavelength of fluorescent of the present element, sensing of NO or pentane is possible.

摘要： A light receiving element provides a current signal corresponding to an amount of received light scattered by suspended particles moving at a predetermined speed to a pulse width measurement circuit and a current-voltage conversion circuit via a filter circuit. A pulse width measured from the current signal is converted into a voltage value based on a predetermined relationship by a pulse width-voltage conversion circuit, and is provided to a voltage comparison circuit. The current-voltage conversion circuit converts a peak value of the current signal into a voltage value, and an amplifier circuit amplifies the signal at a predetermined amplification factor and provides the same to the voltage comparison circuit. The voltage comparison circuit uses the voltage value converted from the pulse width as a boundary value, and the suspended particles causing the scattered light are detected as microorganisms when the peak voltage value is smaller than the boundary value.
