Abstract
The present invention allows a target substance to be detected easily without applying an external magnetic field to a magnetic marker. The present invention provides a target substance detection kit including: a target substance detection board which contains a magnetic sensor and a first target substance capture molecule; and a magnetic marker which contains a magnetic structure and a second target substance capture molecule, wherein the first target substance capture molecule exists on a surface of the target substance detection board, and the magnetic structure generates a magnetic stray field under polarized light.
Claims7
A target substance detection kit comprising:
- a target substance detection board which contains a magnetic sensor and a first target substance capturing body;
- and
- a magnetic marker which contains a magnetic structure and a second target substance capturing body,
- wherein the first target substance capturing body exists on a surface of the target substance detection board, and
- the magnetic structure generates a magnetic stray field under polarized light.
A target substance detection method for detecting the presence or absence of a target substance or an amount of the target substance in a specimen, comprising:
- (i) putting a magnetic marker and the specimen in contact with a target substance detection board which contains a magnetic sensor and a first target substance capturing body and thereby forming a compound which includes the first target substance capturing body, the target substance, and the magnetic marker, the magnetic marker containing a magnetic structure and a second target substance capturing body;
- (ii) illuminating the compound with polarized light;
- and
- (iii) detecting a magnetic stray field generated by the magnetic structure under the polarized light.
