This invention features magnetic sensor based systems and methods for the detection of analytes, such as nucleic acids and pathogens. In particular systems employing an RF pulse in combination with a bias magnetic field methods are featured. Magnetic particles used have a mean particle diameter between 700 and 950 nm, leading to an increased sensitivity as a consequence of increased size aggregates with an increased T2 relaxivity. A removable cartridge for insertion and removal from the system is also described. |
