Electrochemical detection of magnetic particle mobility
First Claim
1. A method for electrochemically monitoring the mobility of particles in a fluid in response to an external field, the method comprising:
- monitoring an electrical characteristic of the fluid in an electrochemical cell, the fluid comprising particles that can be moved under the influence of the external field, wherein the particles are magnetic, wherein the external field comprises a changing external magnetic field;
observing the electrical characteristic caused by the movement of the magnetic particles induced by the external field, wherein the magnitude of the electrical characteristic can change due to a change in the mobility of the magnetic particles; and
detecting a change in the mobility of the magnetic particles from a change in the magnitude of the electrical characteristic observed.
