Abstract: In a detection apparatus, an inlet and an outlet are opened and an air introducing mechanism is driven to introduce air to a case, and airborne particles are electrically attracted and held on a collecting jig 12. After introduction, the inlet and outlet are closed, and amount of fluorescence received by a light receiving element resulting from irradiation with light emitted from a light emitting element is measured by a measuring unit. Thereafter, the collecting jig is heated by a heater and the amount of fluorescence after heating is measured by the measuring unit. Based on the amount of change in the amount of fluorescence before and after heating, the amount of microorganisms collected by the collecting jig is calculated at the measuring unit.

Abstract: 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.

Abstract: A series load circuit is a circuit formed by connecting a light-emitting device unit 851 (the first load circuit) and a light-emitting device unit 852 (the second load circuit) in series. A voltage generating circuit 111 generates voltage to be applied to the series load circuit. A current detecting circuit 112 detects electric current flowing through the light-emitting device unit 851. A controlling circuit 114 controls the voltage generating circuit 111 so that the electric current detected by the current detecting circuit 112 becomes a predetermined current value.

Abstract: A biosensor capable of highly sensitive detection of a recognition target substance while having structural stability is provided at low cost. The biosensor is for capturing and detecting a recognition target substance and includes a linker made of a hydrocarbon compound having two or more particular functional groups, a peptide serving as a molecular recognition substance directly bonded to one particular functional group of the linker, and a support directly bonded to the other particular functional group of the linker. Preferably, the particular functional groups each are a reaction product functional group of an epoxy group and an amino group. The peptide is an artificially synthesized peptide including three or more consecutive amino acid sequences, among amino acid sequences of a natural immunoglobulin, that exist in a part corresponding to a hypervariable area of the natural immunoglobulin.
