Patent attributes
Disclosed herein are devices for molecule detection and methods for using detection devices for molecule detection, such as nucleic acid sequencing. In some embodiments, a detection device comprises one or more pole pieces, one or more sensors, each of the one or more sensors coupled to at least one of the one or more pole pieces, and detection circuitry coupled to the one or more sensors. The detection circuitry is configured to detect a characteristic of each of the one or more sensors, the characteristic indicating presence or absence of one or more magnetic nanoparticles (MNPs) coupled to at least one of a plurality of molecules to be detected, and at least one of the one or more pole pieces is operable to draw the one or more MNPs toward at least one of the one or more sensors.
