First Claim
Patent Images
1. A method for mixing one or more materials on a nano or micro scale, comprising:
- a) adding one or more materials into a vessel;
b) adding magnetic particles into the vessel, wherein the magnetic particles have a particle diameter size of from about 5 nm to about 50 μ
m and are encapsulated in a polymeric shell;
c) applying a varying magnetic field to the magnetic particles to move the magnetic particles to mix the one or more materials in the vessel on a micro or nano scale, wherein the varying magnetic field is biased by another constant magnetic field;
d) mixing the one or more materials in the vessel until a desired particle size is achieved; and
e) collecting the magnetic particles for re-using at a later time.

Abstract
A method and system for magnetic actuated mixing which use magnetic particles and electromagnetic field to facilitate the mixing. The method and system use magnetic particles and a generated electromagnetic field to facilitate the milling as well. The method and system can be used in any application that requires the preparation of small-sized particles at either the micro or nano scale, including for example, preparing toners, inks, wax, pigment dispersions and the like.

10. A method for mixing one or more materials on a nano or micro scale, comprising:
-
a) pre-loading magnetic particles into a vessel, wherein the varying magnetic field is biased by another constant magnetic field and further wherein the magnetic particles have a particle diameter size of from about 5 nm to about 50 μ
m and are encapsulated in a polymeric shell;b) adding one or more materials into the vessel; c) applying a varying magnetic field to the magnetic particles to move the magnetic particles to mix the one or more materials in the vessel on a micro or nano scale, wherein the varying magnetic field is applied from a source external to the vessel; d) mixing the one or more materials in the vessel until a desired particle size is achieved; and e) collecting the magnetic particles for re-using at a later time. - View Dependent Claims (11, 12, 13, 14)
