Sensor, measuring device, and measuring method
First Claim
1. A measuring method for an analyte using a sensor comprising:
- a sample-holding unit including a space for holding a sample including a first analyte comprising an antigen and a second analyte comprising an ion;
a sample-supplying port for supplying said sample to said sample-holding unit, the port being connected to the space;
a detecting unit for carrying out an electrochemical measurement, the detecting unit being provided in said sample-holding unit;
a light-entrance unit for introducing incident light to said sample-holding unit, the light-entrance unit being provided in said sample-holding unit;
a light-exit unit for releasing outgoing light from inside said sample-holding unit to outside said sample-holding unit, the light-exit unit being provided in said sample-holding unit; and
a reagent-holding unit for holding a reagent comprising an antibody for said optical measurement, the reagent-holding unit being provided in said sample-holding unit;
wherein in a flowing direction of said sample supplied from said sample-supplying port in said sample-holding unit, said sample-supplying port, said detecting unit, and said reagent-holding unit are positioned in the order recited;
the method comprising the steps of;
(A) supplying said sample to said sample-holding unit;
(B) applying a voltage to said detecting unit;
(C) measuring an electric-signal from said detecting unit;
(D-1) quantifying said second analyte based on said electric-signal measured in said step (C);
(D-2) causing antigen-antibody reaction between said first analyte in said sample and said antibody held in said sample-holding unit;
(E) applying incident light to said sample held in said sample-holding unit via said light-entrance unit;
(F) measuring outgoing light released from inside said sample-holding unit to outside said sample-holding unit via said light-exit unit, caused by the application of said incident light; and
(G) quantifying said first analyte based on said outgoing light measured in said step (F) and quanitification result of said second analyte.
