DETECTOR AND DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To quantitatively handle the quantity of a specimen as digital data by a simple method because a predetermined output waveform is obtained when the magnetization of magnetic ultrafine particles in a method for detecting the specimen using magnetic particles as labelling particles but this output waveform is obtained corresponding to the magnetization quantity of the whole of magnetic ultrafine particles present in the given region of an inspection reagent and it is impossible to quantitatively handle the amount of an antigen or antibody in the specimen on the basis of the detected waveform. SOLUTION: Magnetic particles are used as the labelling particles and the amount of heat is generated by applying a high-frequency magnetic field to the magnetic particles remaining by biochemical reaction to detect a change in the physical quantity corresponding to the number of the magnetic particles to detect a substance contained in a specimen solution. A target substance such as an antigen or the like is easily and quantitatively detected. COPYRIGHT: (C)2006,JPO&NCIPI
