Abstract
Disclosed is a process for enhancing the sensitivity of magnetic detection of molecules of interest. The process comprises creating amorphous magnetic metal nanoparticles from a bulk target material comprising at least one magnetic transition metal selected from the group consisting of Ni, Co, and Fe and at least one glass former selected from the group consisting of P, B and Si through the use of a pulsed laser ablation method. The produced amorphous magnetic metal nanoparticles have a large magnetic moment and a large magnetic permeability especially compared to crystalline nanoparticles. One use of the present nanoparticles is in a magnetic immunoassay method.
