Abstract
Disclosed herein are detection devices, systems, and methods that use magnetic nanoparticles (MNPs) to allow molecules to be identified. Embodiments of this disclosure include magnetic sensors (e.g., magnetoresistive sensors) that can be used to detect temperature-dependent magnetic fields (or changes in magnetic fields) emitted by MNPs, and, specifically to distinguish between the presence and absence of magnetic fields emitted, or not emitted, by MNPs at different temperatures selected to take advantage of knowledge of how the MNPs' magnetic properties change with temperature. Embodiments disclosed herein may be used for nucleic acid sequencing, such as deoxyribonucleic acid (DNA) sequencing.
