The present invention forms a detection layer in an embedded biosensor probe by using a phenazine derivative as a redox mediator in which a phenazine group is covalently bonded to a high molecular weight polymer having a carboxyl group or an amino group, such as polyamino acid, polyimine, or polyallylamine; and the distance between the phenazine group and the high molecular weight polymer main chain is increased by using a polyethylene glycol chain.

Sensor using phenazine derivative or high molecular weight redox polymer containing phenazine derivative

A sensor insertion device comprises a main body, needle slider, disposal slider, spring, puncture knob, and opening mechanism (window member and handle). The needle slider grips a needle and a sensor on a first end side, and is slidable inside the main body. The disposal slider is slidable inside the main body. The puncture knob has an insertion hole into which the rear end portion of the needle slider can be inserted. The opening mechanism puts the insertion hole into a closed state when the needle slider is being slid in the sensor insertion direction, and, puts the insertion hole in an open state in which the second end side of the needle slider has been inserted into the insertion hole by opening up the contact portion between the puncture knob and the second end side of the needle slider when the puncture operation is complete.
