<p>A magnetic particle based separation and assaying method uses at least two sets of magnetic particles placed in solution within a container and characterized respectively by a coercive field e1 and e2, wherein e1 is greater than e2. The first magnetic particles with a larger coercive field e1 will be used as carrier to handle the second affinity magnetic particles having a lower coercive field e2. A magnetic particles handling method includes the step of applying an external magnetic field having a polarity and amplitude that varies with time to cause the said carrier magnetic particles to be in relative motion within the container driving thereby the affinity particles to form an homogenous suspension of particles in perpetual relative movement with the respect to the liquid.</p> |
