Abstract
Provided are an analysis device and an analysis method. According to the device and the method, a giant magnetoresistance (GMR) sensor unit is formed to be the same as the size of one cancer cell or smaller and magnetic resistance according to the number of magnetic nano particles coupled with the one cancer cell by using the GMR sensor unit, thereby not only diagnosing cancer but also simply and cheaply distinguishing the type of the cancer.
