Abstract: The present disclosure relates to a magnetic trap system (1000) comprising: a microscopic device (300), comprising a principal axis extending in a longitudinal direction; a trap (100) for magnetically confining the microscopic device in a confinement region (CR); a receptable zone (RZ) for receiving biological mattermatter (400, 800), the receptable zone (RZ) comprising the confinement region (CR); a mechanical device (200) for providing a relative movement between the receptable zone (RZ) and the microscopic device (300); wherein the trap (100) is hollow about a longitudinal axis (A), comprises the receptable zone, and provides a magnetic field gradient configured to confine the microscopic device to the confinement region (CR) of the trap (100); wherein the orientation of the magnetic field in the confinement region (CR) is to align the microscopic device in the confinement region (CR) with the longitudinal axis (A) of the confinement region.
