A device for the quantification of cellular and non-cellular components in a blood sample including detection electrodes including a first electrode connected with a first input to receive a first signal in input and a second electrode, reference electrodes including a first electrode connected with a second input configured to receive a second signal in input of opposite polarity to the first input signal and a second electrode connected to the second electrode of said detection electrodes, in a common point wherefrom an output signal is picked up, a ferromagnetic concentrator that cooperates with an external magnetic field external to effectuate concentration of said components on said detection electrodes, a substrate configured to house said detection electrodes, reference electrodes, and concentrator; a support configured to collect a blood sample, and a spacer element to confine in the substrate plane the blood sample and to distance said substrate from said support.

Device and method for the quantification of cellular and non-cellular blood components

A system and a method for the controlled manipulation of any number of magnetic particles in solution are shown. The system and the method of the present invention are based on the employment of magnetic conduits properly structured in order to inject, move and annihilate with high precision magnetic domain walls and on the fact that said magnetic domain walls exert a high attraction force on magnetic particles. The injection, movement and annihilation of domain walls along said magnetic conduit result, therefore, in the trapping, movement and release, respectively, of single magnetic particles placed in solution in proximity of said magnetic conduits. The devices of the present invention guarantee the possibility of a digital transfer of magnetic particles along conduits formed by linear segments as well as high control and nanometric precision in the manipulation of said magnetic particles on curved conduits.
