Claims
- 1. A method of preparing a biomedical implant comprising:mechanical alloying powders of selected metals to prepare non-stoichiometric non-equilibrium nanoscale alloy powders; pressing the nanoscale powders to form the biomedical implant.
- 2. The method of claim 1 wherein the selected metals are non-toxic.
- 3. A method of bio-active material delivery comprising:providing a metal containing substance; converting the metal-containing substance into a non-stoichiometric non-equilibrium crystalline nanomaterial; adding at least one selected bio-active material to the nanomaterial to form a bio-active material loaded nanomaterial; preparing a bio-active material carrying carrier comprising the bio-active material loaded nanomaterial; and implementing bio-active material delivery by administering the bio-active material carrying carrier by a method selected from the group consisting of: oral administration, topical administration, injection and implantation.
- 4. The method of claim 3 wherein the nanomaterial comprises a magnetic material.
- 5. The method of claim 3 wherein the nanomaterial comprises a photocatalytic material.
- 6. The method of claim 3 wherein the bio-active material comprises a drug.
- 7. The method of claim 3 wherein the bio-active material comprises a marker.
- 8. The method of claim 3 further comprising coating the bio-active material loaded nanomaterials with a polymer.
- 9. The method of claim 3 wherein preparing the bio-active material carrying carrier comprises dissolving the bio-active material loaded nanomaterial in a solvent.
