A molecular recognition element comprising a target molecule-recognizing portion, and a direct electron transfer-type oxidoreductase linked to the target molecule-recognizing portion.

Direct electron transfer-type oxidoreductase-modified molecular recognition element

An electrochemical sensor includes a base member, a conductor disposed on the base member, an insulating layer covering the conductor with a portion of the conductor exposed, a silver/silver chloride electrode formed on at least the exposed portion of the conductor, and a water-permeable organic layer covering the silver/silver chloride electrode.

Electrochemical sensor and method for producing electrochemical sensor

A measuring apparatus for measuring a substrate concentration by using a sensor including an enzyme reagent layer includes a state detecting unit that applies a first voltage and a second voltage different from the first voltage to the sensor to detect a state of the enzyme reagent layer based on a difference between a first response current value obtained under application of the first voltage and a second response current value obtained under application of the second voltage.

Measuring apparatus, detection method, electrochemical sensor and measuring system

The present invention provides a sensor insertion and removing device which is user-friendly and which does not cause infection. The sensor insertion and removing device has a sensor; a puncture blade member; a housing which houses the sensor and the puncture blade member; a guide part which is provided within the housing and which glidably supports the puncture blade member; a puncture blade operating part which inserts the sensor under the skin by causing the puncture blade member to glide along the guide part integrally with the sensor, upon delivering the puncture blade member outside the housing to puncture the skin, and which causes the puncture blade member to glide along the guide part in a state of being separated from the sensor, upon removing the puncture blade member from under the skin into the housing, and a sensor operating part which pulls out the sensor from under the skin and removes it from under the skin into the housing.

Sensor insertion/recovery device

The present invention provides an electrochemical sensor comprising a substrate, an electrically conductive layer made of carbon particles which is disposed on the substrate, a cell membrane mimetic structure layer containing an enzyme at least one of inside the cell membrane mimetic structure layer and on the interface of the cell membrane mimetic structure layer which is disposed on the electrically conductive layer.

Electrochemical sensor and method for manufacturing same

When continuous user biometric information is transmitted to a server device continuously from a handheld device used by a user, the server device can be caused to receive a required measurement value efficiently at a required time, select information desired by the user on the basis of the measurement value and user peripheral information, and provide the user with the information reliably, without imposing excessive communication charges and the like. A server deviceis used together with a handheld devicethat transmits the user peripheral information to the server device and receives the information transmitted from the server device. After determining that a fluctuation has occurred in the user peripheral information transmitted from the handheld device, the server deviceperforms either processing for calculating a predicted value of future user biometric information or processing for receiving the predicted value of the future user biometric information, selects information on the basis of the predicted value and the user peripheral information, and transmits the selected information to the handheld device

Information provision system, information provision method, program, and server device

A biosensor includes a first working electrode that a biocatalyst, which has a property that reacts on a specified ground substance, is disposed, a second working electrode that the biocatalyst, which the property is lost, is disposed, and at least one counter electrode for respectively applying a voltage to the first working electrode and the second working electrode.
