  • Patent number: 8906691
    Abstract: A magnetic platform is provided and includes a patterned array of discrete magnetic elements positioned on a substrate, a plurality of first electromagnets for creating a first magnetic field substantially in the plane of the substrate, an electromagnetic coil for creating a second magnetic field substantially perpendicular to the plane of the substrate, and a control device for controlling the application of the magnetic fields. Processes for manipulating, transporting, separating and sorting micro-or nano-scale particles and biomolecules are also described.
    Type: Grant
    Filed: March 14, 2014
    Date of Patent: December 9, 2014
    Assignee: The Ohio State University
    Inventors: Ratnasingham Sooryakumar, Thomas Charles Henighan, Gregory B. Vieira, Jeffrey J. Chalmers
