Superparamagnetic Magnetic Nanoparticle Detection for Early Diagnosis of Neurodegenerative Diseases — •Luca Marnitz, Anastasiia Moskaltsova, Jan Schmalhorst, and Günter Reiss — Center for Spinelectronic Materials and Devices, Physics Department, Bielefeld University, Universitätsstraße 25, 33615 Bielefeld

This talk will introduce a new technique for the early detection of neurodegenerative diseases developed within the H2020 project MADIA [1]. It will focus on the development and integration of magnetoresistive sensors which are able to detect small amounts of superparamagnetic magnetic nanoparticles (SMNPs) with diameters of about 50nm inside a microfluidic channel. For this purpose, sensors based on the Giant Magnetoresistance (GMR), Tunneling Magnetoresistance (TMR) and Planar Hall Effect (PHE) were evaluated regarding their suitability for this purpose. The specific challenges of integrating the sensors in microfluidic lab-on-chip systems will be discussed and the realized solutions will be presented. [1]http://www.madia-project.eu/
