[HTML][HTML] The effect of the particle size and magnetic moment of the Fe3O4 superparamagnetic beads on the sensitivity of biodetection
In recent years, the quantitative detection of biomolecules based on Giant magnetoresistive
(GMR) sensors and magnetic nanoparticles have received continuous attention.
Researchers try to improve the accuracy of detection by various methods, including using a
more sensitive sensor, designing circuit to reduce system noise, and so on. In which, the
intrinsic properties of magnetic labels, such as the particle size of labels is a vital aspect for
the GMR biosensing technology. In this work, a series of Fe 3 O 4 particles with average …
