Abstract

The invention discloses a paramagnetism-based remote temperature measurement method for magnetic nanoparticles, and the method comprises: applying multiple times of excited magnetic fields on the area of a magnetic nano sample, constructing an equation group between the different excited magnetic fields and corresponding magnetic susceptibilities according to the Langevin's paramagnetic theorem, and obtaining the information of temperature and sample concentration via the equation group. The invention is capable of more precisely and more quickly detecting the temperature of an object, and especially applicable for the detection of thermal motion at bio-molecular level. Experiments indicate the measurement error is less than 0.56K.
