This paper reports on a microfluidic platform with an integrated spin valve giant magneto-resistance (GMR) sensor used for the detection and quantification of single magnetic micromarkers. A microfluidic channel containing the magnetic fluid, microconductors (MCs) for collection of the magnetic markers and a spin valve GMR sensor for detecting the presence of their magnetic stray field were integrated on a single chip. The results show that the sensor is capable of detecting a single magnetic marker with 2.8 μm diameter.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
