Summary:A method of detecting a particle comprises magnetizing a particle using an AC magnetic field; generating an AC voltage in a sensing device having a conductive substantially 2-dimensional lattice structure from the magnetized particle; superimposing a DC magnetic field on the generated AC voltage in the sensing device; and measuring an AC Hall voltage at the sensing device.
