OPTIMIZATION OF A NOVEL MAGNETIC NANOPARTICLE SENSOR

Jarkko Mäkiranta, Jukka Lekkala

Abstract

This paper represents an experimental iteration of a novel magnetic nanoparticle (MNP) sensor. MNPs can be used as labels in quantitative diagnostic. Planar microcoils in an impedance bridge are used to measure the amount of the particles. Particles change the inductance of the coil due to their permeability. The shape and size of the coil are critical to the sensitivity and robustness. Experimental measurements supported by numerical simulations have been used in sensor designing, improving and optimization.
