NMR SYSTEMS AND METHODS FOR THE RAPID DETECTION OF ANALYTES

摘要

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.
