Claims
- 1. A magneto-mechanical device for the delivery of substances into a target material comprising:
a) a first surface comprising a plurality of magnetizable particles wherein said magnetizable particles protrude substantially perpendicular from the face of said first surface; b) a second surface substantially parallel to the first surface; c) a target material placed on either surface; d) at least one magnet for positioning said magnetizable particles; and e) a means to bring said first surface and said second surface towards each other whereby magnetizable particles contact said target material so as to cause said particles to penetrate the target material, thereby delivering a substance on said particles into the target material.
- 2. The magneto-mechanical delivery device of claim 1 wherein said device is portable.
- 3. The magneto-mechanical delivery device of claim 1 wherein said magnetizable particles have at least one sharp end.
- 4. The magneto-mechanical delivery device of claim 1 wherein said magnetizable particles are recoverable from said target material.
- 5. The magneto-mechanical delivery device of claim 1 wherein said magnetizable particles are contained in a particle packet.
- 6. The magneto-mechanical delivery device of claim 5 wherein said particle packet also contains target material.
- 7. The magneto-mechanical delivery device of claim 1 wherein said magnetizable particles are contained in a matrix.
- 8. The magneto-mechanical delivery device of claim 7 wherein said matrix also contains target material.
- 9. The magneto-mechanical delivery device of claim 7 wherein said matrix has an adhesive backing.
- 10. The magneto-mechanical delivery device of claim 7 wherein said matrix comprises magnetizable particles mounted in a foil carrier.
- 11. The magneto-mechanical delivery device of claim 7 wherein said matrix is liquid.
- 12. The magneto-mechanical delivery device of claim 7 wherein said matrix is a gel.
- 13. The magneto-mechanical delivery device of claim 7 wherein said matrix is frozen.
- 14. The magneto-mechanical delivery device of claim 1 wherein said means to bring said first and second surfaces towards each other comprises a base and a moveable arm substantially parallel to said base.
- 15. The magneto-mechanical delivery device of claim 14 wherein said moveable arm is retractable.
- 16. The magneto-mechanical delivery device of claim 14 wherein said moveable arm is manually operated.
- 17. The magneto-mechanical delivery device of claim 14 wherein said moveable arm is operated by a clamp, a piston, or a roller.
- 18. The magneto-mechanical delivery device of claim 14 wherein said moveable arm has a limiting means.
- 19. The magneto-mechanical delivery device of claim 18 wherein said limiting means is adjustable.
- 20. A particle pack for the magneto-mechanical transfer of substances to a target material comprising magnetizable particles contained in a matrix.
- 21. The particle pack of claim 20, wherein said matrix also contains target material.
- 22. The particle pack of claim 20, wherein said matrix comprises an adhesive backing.
- 23. The particle pack of claim 20 wherein said matrix comprises magnetizable particles mounted in a foil carrier.
- 24. The particle packet of claim 20 wherein said matrix is a liquid.
- 25. The particle packet of claim 20 wherein said matrix is a gel.
- 26. The particle packet of claim 20 wherein said matrix is frozen.
- 27. A method for delivering substances into a target material using a magneto-mechanical delivery device comprising the steps of:
a) placing magnetizable particles on a first surface, wherein said magnetizable particles protrude substantially perpendicular from the face of said first surface; b) introducing said magnetizable particles to a target material by bringing said first surface towards a second surface which is substantially parallel to said first surface such that said particles contact said target material; and c) maintaining contact sufficient to allow the magnetizable particles to penetrate said target material, thereby delivering a substance on said particle into said target material.
- 28. The method of claim 27 wherein the magnetizable particles are treated with the substance to be introduced into said target material prior to loading.
- 29. The method of claim 27 wherein the target material is treated with the substance to be introduced, prior to loading.
- 30. The method of claim 27 wherein at least one magnet is used to position said magnetizable particles.
- 31. The method of claim 27 wherein at least one electromagnet is used to position said magnetizable particles.
- 32. The method of claim 27 further comprising the step of placing the magnetizable particles in a matrix.
- 33. The method of claim 32 wherein said matrix also contains target material.
- 34. The method of claim 32 wherein said matrix comprises an adhesive backing.
- 35. The method of claim 32 wherein said matrix comprises magnetizable particles mounted in a foil carrier.
- 36. The method of claim 32 wherein said matrix is a liquid.
- 37. The method of claim 32 wherein said matrix is a gel.
- 38. The method of claim 32 wherein said matrix is frozen.
- 39. The method of claim 27 wherein said particles are recovered from the target material.
