    Abstract: The present invention relates to a biomolecular measurement system (1), which enables to measure the intermolecular forces arising from the interaction between two biomolecules or the intramolecular forces within a single biomolecule by using an atomic force microscope (AFM). In the present invention, the cantilever (2) is moved without using an actuator for moving the cantilever (2). It is moved only when the actuator (4) moves the magnetic nanowire (3) and thus moves the molecule attached to the end of the magnetic nanowire (3). Since the cantilever (2) or a substrate is not moved by another actuator as in the state of the art, fluctuation and disturbance is not created in the liquid containing the biomolecules. Thus, the measurements are made more accurately and with higher resolution. Additionally, by means of the actuator (4), the biomolecules are enabled to be moved upon exertion of magnetic force at any coordinate on x, y and z axes on the nanowire (3), or exertion of torque on two axes.

    Abstract: Methods, systems and programing for substance detection with a magnetic sensor are presented. In one example, a magnetic sensor having one or more layers is formed on a base for sensing a magnetic field created by magnetic particles present in proximity to the magnetic sensor. A first end of each of a first set of strands is immobilized with respect to the magnetic sensor. A magnetic particle is attached to a second end of each of the first set of strands so that when a material containing a substance is in contact with the base, the substance causes at least some of the first set of strands to break resulting in that the magnetic particle attached to the second end of each of the at least some of the first set of strands is no longer in proximity to the magnetic sensor.

    Abstract: Disclosed herein are systems and methods for using the controlled movement of magnetic particles using controlled magnetic fields in a fluidic device containing separated fluidic regions to detect analytes in solution by immunoassay, such as an enzyme-linked immunosorbant assay (ELISA) for various medical and scientific applications. In order to achieve sequential exposure to the different chemical environments required in an immunoassay, magnetic particles are driven through fluid-containing chambers separated by air-gaps that may take the form of air bubbles or small open-air separations, for example. Externally controlled magnets coupled to actuators draw the flow of magnetic particles through air-liquid interfaces produced by microfluidic surface tension at the air-gap, washing the particles.
