Magnetic particles are distributed across a fluid flow by applied magnetic field to interact with a test substance in fluid. Alternatively or additionally, particles, which may be magnetic, are combined with cells and energy, e.g. ultrasonic energy, is applied to cause the particles to create a lysate. Alternatively or additionally, the size of a quantity of magnetic particles is assessed by its impact on the tuning mechanism of a controlled oscillator that is affected by the particles.
